Overview of a Novel UTI Treatment Device for Women

Urinary tract infections (UTIs) are a common and often recurring issue for many women, leading to discomfort and requiring frequent antibiotic treatment. To address this, an innovative medical device has been conceptualized, designed to be inserted into the urinary tract where it directly combats bacteria through a unique mechanism involving nanostructure spikes. This self-administered device combines advanced materials science with user-friendly design, offering a promising new approach to UTI treatment.

Device Design and Functionality

Nanostructured Mechanism: The core of the device’s functionality lies in its nanostructure spikes, which are made from electro-active polymers shaped into an A-frame. These spikes are capable of vibrating at a microscopic level when activated by an electromagnetic (EM) field. This vibration allows the spikes to effectively disrupt and kill bacteria on contact, offering a targeted approach to eliminating the infection.

Safety Features: To ensure the device is safe for use within the sensitive environment of the urinary tract, it is equipped with biocompatible filaments. These filaments serve a dual purpose: they prevent the nano-spikes from making direct contact with the bladder walls, thus avoiding tissue damage, and they expand in the presence of bodily fluids to anchor the device temporarily within the urinary tract.

Power Source: The device is powered by a thin, flexible polymer battery, enhanced with inductive charging capabilities. An external, wearable EM emitter, discreetly worn under clothing, supplies the necessary power through an inductive field, thus eliminating the need for wires or direct electrical connections.

Insertion and Usage

Applicator Design: The device is pre-loaded into a sterile, single-use applicator similar to a tampon applicator, ensuring ease of insertion and sterility. The applicator allows for precise placement of the device within the urethra, which can be performed by the user herself in the comfort of her home.

User Experience: After washing her hands, the user unwraps the applicator, inserts it, and deploys the device with a simple push of a plunger. The process is designed to be as simple and pain-free as possible, with detailed instructions provided to ensure correct usage.

Post-Insertion: Once inserted, the device operates independently. After a predetermined period, typically a few days, the filaments degrade, and the device is designed to be naturally expelled during urination. Throughout this period, the device actively combats the bacteria causing the UTI.

Disposal and Environmental Considerations

The applicator and any external packaging are designed to be environmentally friendly, using biodegradable materials where possible, and are disposed of in a sanitary manner.

Conclusion

This novel UTI treatment device offers a revolutionary approach to managing urinary tract infections in women. By combining advanced technology with user-centered design, it provides an effective, safe, and user-friendly alternative to traditional treatments. It represents a significant step forward in personal healthcare, potentially reducing the reliance on antibiotics and decreasing the recurrence of infections.

Future Applications

While the current design is optimized for female anatomy, a similar device could potentially be developed for men, although the method of insertion might require professional assistance due to anatomical differences.

Female Anti-Ageing via Uterine Upcycling as a Stem Cell Farm

Autonomous Stem Cell Cultivation in the Uterine Sandbox: A Novel Approach to Women-Specific Regenerative Medicine

Abstract:
Stem cell therapies hold immense promise for regenerative medicine and aging reversal, but current approaches face challenges in terms of precision control, targeted delivery, and long-term safety. Here, we propose a novel strategy that harnesses the unique properties of the post-reproductive uterus as a site for autonomous, AI-guided stem cell cultivation and delivery using advanced Tethered Non-Cellular Organism (TNCO) technology. By creating a controlled microenvironment within the uterus that mimics the complex signaling landscapes of physiological stem cell niches, TNCOs can support the growth and differentiation of stem cells, and precisely deliver them to target tissues to replace aging or damaged cells. This uterine sandbox approach offers a potentially powerful new platform for women-specific regenerative medicine.

Introduction:
Regenerative medicine aims to replace or regenerate human cells, tissues, or organs to restore normal function. Stem cells, with their capacity for self-renewal and differentiation into diverse cell types, are a key tool in this pursuit. However, current stem cell therapies face several challenges, including the risk of tumorigenesis, immune rejection, and the difficulty of targeted delivery to specific tissues.

We propose a novel approach that addresses these challenges by leveraging the unique properties of the post-reproductive uterus as a site for stem cell cultivation and delivery. By creating a controlled microenvironment within the uterus using advanced TNCO technology, we can potentially enable autonomous, AI-guided stem cell growth and differentiation, and precisely deliver the resulting cells to target tissues to replace aging or damaged cells.

The Uterine Sandbox Concept:
The uterine sandbox is envisioned as a contained microenvironment within the post-reproductive uterus that supports the cultivation of stem cells. This microenvironment would be engineered and maintained by TNCOs, synthetic constructs that can be programmed to perform complex biological functions and guided by artificial intelligence.

Within the sandbox, TNCOs would create and dynamically regulate the conditions necessary for stem cell self-renewal and controlled differentiation. This would involve the precise spatiotemporal delivery of growth factors, extracellular matrix components, and other signaling molecules, as well as the control of physical parameters such as oxygen tension and mechanical stimuli.

Stem Cell Cultivation:
In the body, stem cell maintenance and differentiation are regulated by complex signaling networks involving the nervous system, endocrine system, and local tissue microenvironments. The spinal cord, in particular, is a major hub for neural stem cells and plays a key role in regulating their behavior.

However, for our uterine sandbox approach, we aim to create an artificial microenvironment that can support stem cell growth and differentiation independently of these normal physiological signals. This involves providing the necessary growth factors, nutrients, extracellular matrix components, and other biochemical and biophysical cues to promote stem cell self-renewal and controlled differentiation.

Key considerations for optimizing stem cell culture in the uterine sandbox include:

1. Growth factors: Stem cells require specific growth factors to maintain their undifferentiated state and guide their differentiation into desired cell types. These could include leukemia inhibitory factor (LIF), fibroblast growth factors (FGFs), and transforming growth factor beta (TGF-β) family members, among others. The TNCO system could be designed to continuously secrete these factors into the sandbox microenvironment.
2. Extracellular matrix: The physical and biochemical properties of the extracellular matrix (ECM) play a critical role in regulating stem cell behavior. The TNCO sandbox could be engineered to provide an ECM that mimics the native stem cell niche, with appropriate stiffness, porosity, and bioactive ligands to support stem cell adhesion, growth, and differentiation.
3. Oxygen tension: Stem cells often reside in hypoxic niches in vivo, and low oxygen tension has been shown to promote stem cell self-renewal and pluripotency. The TNCO system could potentially create a controlled hypoxic microenvironment within the sandbox to enhance stem cell maintenance.
4. Metabolic regulation: Stem cell metabolism is tightly coupled to their self-renewal and differentiation capacity. By regulating the availability of key metabolic substrates like glucose, amino acids, and lipids, the TNCO system could potentially modulate stem cell behavior and fate.
5. Mechanical stimuli: Physical forces and mechanical stimuli can also influence stem cell behavior. The TNCO system could potentially incorporate mechanisms for applying controlled mechanical stimulation to the cultured stem cells, such as stretch, compression, or shear stress, to guide their growth and differentiation.

By carefully designing the sandbox microenvironment and leveraging the capabilities of TNCOs to provide precise, localized control over these various parameters, it should be possible to create an optimized niche for stem cell cultivation within the uterus.

TNCO-Mediated Stem Cell Cultivation:
The versatility and programmability of TNCOs, coupled with AI control, opens up a vast design space for engineering customized microenvironments for stem cell cultivation within the uterine sandbox.

As long as the necessary molecular building blocks are available, TNCOs could potentially synthesize and deliver a wide range of growth factors, ECM components, and other signaling molecules on demand. By modulating the spatiotemporal patterns of these factors, TNCOs could create dynamic microenvironments that mimic the complex signaling landscapes of physiological stem cell niches.

Potential ways TNCOs could be leveraged for this purpose include:

1. Programmable secretion: TNCOs could be engineered with synthetic gene circuits that allow for the controlled expression and secretion of desired factors. The AI system could dynamically adjust the expression levels based on real-time monitoring of the cultured stem cells.
2. Molecular patterning: By precisely controlling the spatial arrangement of TNCOs within the sandbox, the AI system could create intricate molecular gradients and patterns that guide stem cell behavior. This could include setting up localized niches with distinct factor compositions to promote different stages of stem cell differentiation.
3. Adaptive feedback control: The AI system could continuously monitor the state of the cultured stem cells using various molecular and biophysical sensors. Based on this data, it could adaptively adjust the TNCO-mediated microenvironment to maintain optimal conditions for stem cell growth and differentiation.
4. Biomaterial scaffolds: TNCOs could potentially assemble and remodel biomaterial scaffolds within the sandbox to provide a 3D structural framework for stem cell growth. By dynamically adjusting the composition and architecture of these scaffolds, the AI system could guide stem cell organization and tissue patterning.
5. Metabolic regulation: TNCOs could potentially control the local metabolic environment within the sandbox by selectively delivering or sequestering key metabolic substrates. This could allow for precise regulation of stem cell metabolic states to influence their self-renewal and differentiation behavior.

The ability to engineer such highly customized and dynamically controlled microenvironments could potentially enable a level of precision and control over stem cell behavior that is not possible with current culture methods. By leveraging the AI-guided capabilities of TNCOs, we could potentially create truly autonomous stem cell cultivation systems that can adapt and optimize themselves in real-time to maintain ideal conditions for stem cell growth and differentiation.

Targeted Delivery and Regenerative Therapy:
Once the desired stem cells have been cultivated within the uterine sandbox, TNCOs can be deployed to precisely deliver these cells to target tissues throughout the body. The uterus provides a unique advantage for this process due to its rich blood supply and vascular connections to the rest of the body. The TNCOs, loaded with the cultured stem cells, can be released into the uterine vasculature, allowing them to navigate through the bloodstream to reach specific target sites.

Guided by the AI system, the TNCOs can use a combination of molecular sensors and navigation mechanisms to home in on areas of aging, damage, or dysfunction. These could include:

1. Chemotactic sensors: TNCOs could be engineered to detect and follow gradients of specific molecular markers released by aging or damaged tissues, such as inflammation-associated cytokines, oxidative stress markers, or tissue-specific factors.
2. Molecular targeting: TNCOs could be surface-functionalized with antibodies or aptamers that bind to specific cell surface receptors or extracellular matrix components overexpressed in target tissues.
3. Imaging guidance: The AI system could potentially integrate data from in vivo imaging modalities (e.g., MRI, PET, ultrasound) to guide TNCOs to specific anatomical locations.

Once at the target site, the TNCOs could use a variety of mechanisms to replace old or dysfunctional cells with the newly cultivated stem cells:

1. Cell fusion: TNCOs could potentially induce the fusion of the carried stem cells with the target cells, transferring healthy organelles and molecular components to rejuvenate the aged or damaged cells.
2. Cell replacement: TNCOs could use their onboard molecular tools to selectively eliminate the old or dysfunctional cells (e.g., through targeted apoptosis induction), and then release the cultured stem cells to take their place.
3. Paracrine signaling: Even without direct cell replacement, the stem cells delivered by the TNCOs could secrete a variety of growth factors, cytokines, and extracellular vesicles that promote tissue repair and regeneration.

Importantly, the AI system would continue to monitor the integration and function of the delivered stem cells over time. This could involve:

1. Molecular surveillance: TNCOs could be engineered to detect specific molecular markers of cell health, differentiation status, and function, and report this data back to the AI system.
2. Functional monitoring: The AI system could potentially integrate data from various physiological sensors and functional tests to assess the impact of the delivered stem cells on tissue and organ function.
3. Safety monitoring: Crucially, the AI system would be vigilant for any signs of aberrant behavior in the delivered stem cells, such as uncontrolled proliferation, off-target migration, or inappropriate differentiation.

If any issues are detected, the AI system could deploy TNCOs to the problematic site to eliminate the misbehaving cells. This could involve targeted delivery of apoptosis-inducing signals, recruitment of the immune system, or physical removal of the cells.

To facilitate long-term monitoring and maintenance, the stem cells could potentially be engineered with molecular “use by dates” – genetic circuits that cause the cells to express specific surface markers or secrete particular factors after a certain period of time or number of cell divisions. This would allow the AI system to easily identify cells that are due for replacement, and target them for removal and replenishment with freshly cultivated stem cells from the uterine sandbox.

The uterus is ideally suited to serve as the hub for this stem cell cultivation and delivery process. Its rich blood supply and direct connections to the systemic circulation provide a natural route for the TNCOs to navigate throughout the body. The uterine vasculature could potentially be engineered with molecular “docking stations” that allow the TNCOs to easily enter and exit the bloodstream as needed.

Furthermore, the uterine environment provides a unique immunological niche that could potentially help to protect the cultivated stem cells from immune recognition and rejection as they are deployed throughout the body. By leveraging the natural immunosuppressive properties of the uterus, the stem cells could potentially be delivered without the need for harsh immunosuppressive drugs.

In many ways, the female reproductive system seems almost tailor-made for this kind of regenerative therapy approach. By harnessing the unique properties of the uterus and the power of TNCO and AI technologies, we have the opportunity to develop a truly revolutionary platform for women’s health and longevity.

Benefits and Potential Applications:
The uterine sandbox approach, enabled by TNCO technology, offers several potential benefits for women-specific regenerative medicine:

1. Autonomous, AI-guided stem cell cultivation and delivery
2. Precise control over stem cell microenvironment and behavior
3. Minimally invasive, localized regenerative interventions
4. Reduced risk of tumorigenesis or immune rejection
5. Potential for long-term, adaptive regenerative therapies

Potential applications could include the treatment of age-related diseases, tissue regeneration following injury or disease, and general healthspan and lifespan extension.

Challenges and Future Directions:
Realizing the full potential of the uterine sandbox approach will require significant advancements in TNCO engineering, AI control systems, and stem cell biology. Key challenges include:

1. Developing robust methods for programming TNCOs to synthesize and deliver complex biological factors
2. Creating sophisticated AI algorithms for real-time microenvironment control and stem cell monitoring
3. Validating the safety and efficacy of the approach in rigorous in vivo studies
4. Addressing potential ethical concerns around uterine interventions and autonomous regenerative therapies

Future research should focus on addressing these challenges through interdisciplinary collaborations spanning synthetic biology, AI, biomaterials, and regenerative medicine. By iteratively refining and optimizing the uterine sandbox system, we can potentially create a powerful new platform for women-specific regenerative therapies.

Conclusion:
The uterine sandbox concept, enabled by advanced TNCO technology and AI control, represents a novel and potentially transformative approach to women-specific regenerative medicine. By harnessing the unique properties of the post-reproductive uterus and creating autonomous stem cell cultivation systems within the body that mimic the complexity of physiological stem cell niches, we can potentially unlock powerful new ways to combat aging and promote healthy longevity.

Of course, safety is paramount, and rigorous testing would be needed to ensure that the TNCOs and the AI control system are able to maintain tight control over the delivered stem cells and prevent any potential adverse effects. However, the potential benefits are immense – the ability to precisely target and regenerate aging or damaged tissues throughout the body, using the patient’s own stem cells, cultivated in a natural and immunologically privileged niche.

This represents a novel and potentially transformative approach to regenerative medicine, one that could have profound implications for women’s health and longevity. By developing this technology, we may be able to offer women a new lease on life, allowing them to maintain their vitality and well-being well into old age. It’s an exciting and promising avenue of research that deserves further exploration and development.

While significant challenges remain, the potential benefits of this approach warrant focused research and development efforts. With continued innovation and collaboration across disciplines, the uterine sandbox could become a key tool in the quest to extend healthspan and lifespan, offering new hope for women seeking to maintain their vitality and well-being throughout life. The ability to engineer highly customized and dynamically controlled microenvironments using TNCOs and AI guidance could enable a level of precision and control over stem cell behavior that is not possible with current methods, paving the way for truly transformative regenerative therapies.

The future for women

The future for women, pdf version

It is several years since my last post on the future as it will affect women so here is my new version as a pdf presentation:

Women and the Future

The future of women in IT

 

Many people perceive it as a problem that there are far more men than women in IT. Whether that is because of personal preference, discrimination, lifestyle choices, social gender construct reinforcement or any other factor makes long and interesting debate, but whatever conclusions are reached, we can only start from the reality of where we are. Even if activists were to be totally successful in eliminating all social and genetic gender conditioning, it would only work fully for babies born tomorrow and entering IT in 20 years time. Additionally, unless activists also plan to lobotomize everyone who doesn’t submit to their demands, some 20-somethings who have just started work may still be working in 50 years so whatever their origin, natural, social or some mix or other, some existing gender-related attitudes, prejudices and preferences might persist in the workplace that long, however much effort is made to remove them.

Nevertheless, the outlook for women in IT is very good, because IT is changing anyway, largely thanks to AI, so the nature of IT work will change and the impact of any associated gender preferences and prejudices will change with it. This will happen regardless of any involvement by Google or government but since some of the front line AI development is at Google, it’s ironic that they don’t seem to have noticed this effect themselves. If they had, their response to the recent fiasco might have highlighted how their AI R&D will help reduce the gender imbalance rather than causing the uproar they did by treating it as just a personnel issue. One conclusion must be that Google needs better futurists and their PR people need better understanding of what is going on in their own company and its obvious consequences.

As I’ve been lecturing for decades, AI up-skills people by giving them fast and intuitive access to high quality data and analysis tools. It will change all knowledge-based jobs in coming years, and will make some jobs redundant while creating others. If someone has excellent skills or enthusiasm in one area, AI can help cover over any deficiencies in the rest of their toolkit. Someone with poor emotional interaction skills can use AI emotion recognition assistance tools. Someone with poor drawing or visualization skills can make good use of natural language interaction to control computer-based drawing or visualization skills. Someone who has never written a single computer program can explain what they want to do to a smart computer and it will produce its own code, interacting with the user to eliminate any ambiguities. So whatever skills someone starts with, AI can help up-skill them in that area, while also helping to cover over any deficiencies they have, whether gender related or not.

In the longer term, IT and hence AI will connect directly to our brains, and much of our minds and memories will exist in the cloud, though it will probably not feel any different from when it was entirely inside your head. If everyone is substantially upskilled in IQ, senses and emotions, then any IQ or EQ advantages will evaporate as the premium on physical strength did when the steam engine was invented. Any pre-existing statistical gender differences in ability distribution among various skills would presumably go the same way, at least as far as any financial value is concerned.

The IT industry won’t vanish, but will gradually be ‘staffed’ more by AI and robots, with a few humans remaining for whatever few tasks linger on that are still better done by humans. My guess is that emotional skills will take a little longer to automate effectively than intellectual skills, and I still believe that women are generally better than men in emotional, human interaction skills, while it is not a myth that many men in IT score highly on the autistic spectrum. However, these skills will eventually fall within the AI skill-set too and will be optional add-ons to anyone deficient in them, so that small advantage for women will also only be temporary.

So, there may be a gender  imbalance in the IT industry. I believe it is mostly due to personal career and lifestyle choices rather than discrimination but whatever its actual causes, the problem will go away soon anyway as the industry develops. Any innate psychological or neurological gender advantages that do exist will simply vanish into noise as cheap access to AI enhancement massively exceeds their impacts.

 

 

Has the sisterhood forgotten older women?

We just went through International Women’s Day and I was one of many people asked to write an essay on the above topic for a compendium of essays for the International Longevity Centre, highlighting problems faced by older women and asking if they have been forgotten by feminism.

The pdf of the whole compendium is downloadable from

The future of women in work

Women v men: the glass ceiling is full of holes

Most people I think would agree that at least in the West. the glass ceiling stopping women getting to the top maybe hasn’t vanished but has at least huge gaping holes in it. Most big companies and organisations have anti-discrimination policies, and many go as far as having have quotas and other forms of positive discrimination. There are still some where women get a second class deal, but not many now. So assuming that the war is almost won on that front, what does the future hold for women in work? Well, mixed news I think, some good and some bad.

Winner and loser industries

Technology tends not to have all its impact in one lump, rather working over decades to accomplish its full impacts. Such it is with Artificial intelligence and robotics. Lots of manufacturing shop floor jobs have already been gradually replaced by robotics, with more impact to come, and many analytical and professional tasks will gradually be displaced by AI, with many others outsourced. Traditionally male-dominated jobs are being hardest hit and will continue to be, while gender neutral or female-dominated jobs such as policing, social work, sales and marketing, teaching, nursing etc will hardly be affected. Many of the men made redundant will be able to readjust and re-skill, but many will find it hard to do so, with consequent social strains.

Just as power tools have reduced the economic advantage of being physically strong, so future AI will reduce the economic advantage of being smart. What is left is dominated by essentially emotional skills, and although the polarisation certainly isn’t complete here by any means, this is traditionally an area where women dominate.

Looking at this over the whole spectrum, this pic shows some example areas likely to suffer v those that will flourish. Obviously I can’t list every bit of the entire economy.The consequences of AI are mainly influenced by the fact that few jobs are 100% information processing or intellect. Some is usually interpersonal interaction. Administrators will find that the pen-pushing and decision parts of their jobs will decline, and they will spend more of their time on the human side, the emotional side. Professionals will find that they spend more time with clients dealing with the relationship. Managers will spend more time on motivation, leadership and nurturing. Interpersonal skills, emotional skills, empathy, sympathy, caring, leadership, motivation – these are the primary skills human will provide in the AI world. The information economy will decline and gradually be replaced by the ‘care economy’. Although men can and do offer some of the skills in this list, it is clear that many are more associated with women, so the clear conclusion is that women will acquire an increasing dominance in the workplace.

Global v local

However, another consequence of the same forces is that globalisation of work will start to reverse in some fields, because if high quality human contact is essential part of the job, it is harder to do it from a distance. Some jobs require actual physical contact and can’t be done except by someone next to the customer. Looking at a diverse basket of forces, this is how it works out:Another trend in favour of women is that with increasing restructuring or businesses around small cooperatives of complementarily skilled people, networking is an increasingly important skill.

Low pay will still be an issue

Although women will generally have an easier time than men if emotional skills dominate, the evidence today is that most such work is not highly paid, so even though women will have less difficulty in finding work, it will not be high paid work. High end interpersonal skills such as senior management will fare better, but with extensive industry restructuring, there may be less need for senior managers.

Polarisation of pay

In spite of these trend that affect the vast majority of people, star performers aren’t affected in the same way. Although the markets are already depressing wage levels for groups where there is a lot of supply available, the elite are being rewarded more and more highly, and this trend will continue. The hard facts of life are that a very few individuals make a real difference to the success or failure of a company. The superstar designer, scientist, market analyst, manager or negotiator can make a company win. Letting them go to the competition is business suicide, so they justify and demand high remuneration. Sadly, 99%of us are outside the top 1%. Think about it. There are 70 million people in the global top 1%. Even spread across every sector, and ignoring those too young or old to work, that is stiff competition.

Market gender neutrality

Especially on a large scale, the marketplace is essentially gender neutral in the sense that customers generally don’t care whether a business is run by men or women (it certainly isn’t neutral in the mix of male and female customers for particular products and services of course). The market cares about marketing, price, quality, availability and location and a few other things. Gender has little impact. Companies can’t survive on the gender make-up of their staff, only results really count in the market.

Turbulence in the market caused by rapidly changing technology, especially IT, accelerates levelling of the playing field by favouring new business models and adaptable companies and wiping out those that can’t or won’t adapt. By contributing to accelerating change, IT thus acts in accelerating the downfall of a patriarchal business environment in favour of one based purely on merit. It expedites the end of the war of women v men but when it runs to completion, women will play against men and against each other on a truly level playing field.

Women v women: attractive v plain, young v old

Now that the glass ceiling is less of an issue, the battleground is moving on to appearance discrimination, which obviously links to age too. We now often hear older or plainer women complaining that the best jobs are going to pretty young things instead of the more experienced women who sadly have left their prettier days behind, especially in high profile media and customer facing jobs.

A real world example illustrates the problem well. A while back, the BBC’s treatment of older women was ruled discriminatory by the courts because they had favoured attractive younger women to put in front of cameras over older, less attractive ones. However fair it might be, such a ruling puts the customer in conflict with the regulator. Although such a ruling may appear fair, actually all the female presenters lose, as viewers will simply swap channels to programmes hosted by presenters they want to watch. The trouble is that regulators can rule how companies must behave internally, but they can’t prevent customers from using their free choice what to buy. If some viewers prefer to watch attractive young news readers, they can and will. Those programmes hosted by less attractive ones will see a reduction in viewer numbers, and consequential drop in revenue from advertising on those programmes, or in the BBC’s case, just a drop in viewers. Unless the customer has no choice in what they watch, the courts can’t level the playing field.

It isn’t just on TV that such discrimination occurs, but throughout industry. In male dominated areas, with mostly men at the top, attractive women will be favoured at interview time, and will then tend to dominate senior posts, so that quotas can be filled but men get to choose which women fill them. In airlines, it is hard not to notice if you fly frequently, that the most attractive stewardesses end up in first and business class, with the less attractive and older ones serving the economy cabin. And on a front reception desk, bar, sales jobs, and PR, attractive women have an obvious advantage too.

It looks as if this issue is likely to dominate as we move into an economy where women as a whole have the advantage over men. And it will be much harder to legislate equality in this case.

Experience v looks & IQ

With the pension crisis growing daily, it is inevitable that people will have to work longer than today. Social skills tend to grow with age and experience in contrast with intellectual speed and agility and physical beauty, which tend to decline with age. This is a fortunate trend as it enables work to be done by older people at just the time that retirement age will have to increase.
