Taking Control Why Medical Knowledge Matters More Than Ever After 60

The Hidden Cost of Medical Knowledge Gaps

The endocannabinoid system regulates pain, sleep, anxiety, and overall body balance in every human being. It's been scientifically documented since 1988. Yet Dr. Michael Best practiced medicine for 50 years without learning about it. And your doctor probably hasn't either.

This knowledge gap sits at the heart of a larger crisis facing professionals over 60: the dangerous assumption that medical practitioners possess comprehensive, current scientific knowledge about our aging bodies. They don't. And this ignorance has direct consequences for our cognitive vitality, professional capability, and quality of life in later years.

The Pattern Emerges: Two Experts, Same Problem

Two recent Wisepreneurs conversations reveal a disturbing pattern. Amy Alkon, investigative science writer and author of Going Menopostal, spent eight years researching menopause because her doctors couldn't provide evidence-based care. Dr. Michael Best discovered medicinal cannabis research at 74, realising an entire biological system had been omitted from his medical education.

Both encountered the same institutional failure: medical schools don't train doctors to read and evaluate research. Medical practitioners lack time to study new findings. Regulatory bodies move glacially while patients suffer from treatable conditions.

"There are three big myths about our medical care that we believe: one is that doctors make decisions according to scientific evidence and that they can read and evaluate it. The other is that they're trained in diagnostic reasoning, and the third is that they can properly assess risk. And none of those are the case." — Amy Alkon

For Alkon, this meant fighting multiple battles to access appropriate hormone therapy, armed with research her doctors hadn't read. For Best's patients, it meant years of chronic pain before discovering treatments their GPs dismissed as unproven despite thousands of studies.

The common thread: accumulated professional wisdom became the evaluative framework that made self-advocacy possible. Both leveraged decades of expertise—Alkon's investigative rigour, Best's medical training—to navigate knowledge gaps their doctors couldn't bridge.

Why Cognitive Performance Depends on Physical Health

Brain fog, memory loss, and diminished executive function often signal treatable physiological issues, not inevitable decline. Yet when professionals over 60 report these symptoms, they're frequently dismissed as "normal aging" or stress rather than investigated as potential hormonal, metabolic, or inflammatory problems.

Alkon describes losing her cognitive edge during perimenopause:

"I would have to ask Eric sitting next to me, what, what's your number? Because I would say my number and I would forget. I mean, this is horrible." 

Her doctors suggested it was psychological. The actual cause: inadequate progesterone disrupting sleep, preventing the cerebral spinal fluid from washing neural waste from her brain during deep sleep cycles.

"These vital, important, powerful, accomplished professional women, they lose their power at work, you know, to function even, you know, and they don't know it's perimenopause and other people don't. They think they're lazy or drunk or, you know, something's wrong with them in some kind of pernicious way." — Amy Alkon

Dr. Best's cannabis patients reported similar cognitive improvements when chronic pain, anxiety, or sleep disturbances were properly addressed. The endocannabinoid system directly affects neurological function, yet mainstream medicine largely ignores it. As Best explains:

"The system inside us does just about everything. It's the most extraordinary system. And in particular, it's there to help us to protect against pain. It's there to help us relax. It's there to help us to sleep."

These aren't edge cases. They're examples of how systemic medical ignorance specifically harms older professionals whose cognitive performance defines their professional value. When brain fog is dismissed rather than investigated, careers end prematurely. When memory issues are attributed to age rather than hormonal disruption, decades of expertise goes to waste.

Your ability to work at a high cognitive level—to synthesise information, recognise patterns, make strategic decisions, and leverage accumulated wisdom—depends fundamentally on physiological health.

Sleep quality affects memory consolidation. Hormonal balance influences executive function. Inflammatory markers predict cognitive decline. These aren't separate issues from professional capability; they're the biological foundation that makes sustained intellectual work possible.

The Agency Imperative: Why Passive Patients Fail

Traditional patient behaviour—trusting doctors, following recommendations, accepting reassurances—proves inadequate when medical knowledge lags decades behind research. Both Alkon and Best emphasise that patients must take agency over their health, but this requires strategic capability most people lack.

Alkon calls it "defensive patienting"—understanding how doctors interpret data so you can present information in ways that overcome their knowledge gaps. Best describes using AI tools as research partners, evaluating outputs against 50 years of medical experience to separate valid information from hallucinations.

"With the experience you had, especially the knowledge that you have, you are able to look at the output from the ChatGPTs and Claude. You're able to evaluate it, you've got your knowledge and you can assess whether it's what's called hallucinating." — Nigel Rawlins to Dr. Best

I am not trying to encourage you to become amateur doctors. My intention is to suggest leveraging yoour accumulated professional intelligence to:

• Recognise when explanations don't make physiological sense. Alkon knew "super-physiologic dose" was wrong when simple math showed she metabolised estrogen at half the normal rate. Best recognised that recreational cannabis users accessing legal medical prescriptions created regulatory challenges, not medical ones.
• Distinguish between institutional limitations and individual health needs. Just because your healthcare system's formulary doesn't include optimal treatment options doesn't mean you should accept substandard care. Just because regulatory bodies haven't approved a treatment for your condition doesn't mean research shows it won't help.
• Evaluate research quality without becoming a statistician. Both developed frameworks for assessing study validity—Alkon through coaching from a top epidemiologist, Best through deep dives into endocrinology textbooks. The goal isn't mastering research methodology but developing sufficient literacy to spot obvious flaws.
• Present medical data doctors can't dismiss. Alkon's quantitative basal temperature testing provided objective evidence of progesterone deficiency. Best's patients brought documentation of symptom improvement that opened specialists' minds to possibilities they'd initially rejected.

"I can't sleep is the best. Not that I tell people to lie, but you probably are not sleeping if you're having this problem. You need sleep—you die without sleep and you can't function without sleep." — Amy Alkon on strategic patient advocacy

The Technology Advantage: Why Age Becomes Asset

Dr. Best learned Obsidian, Zotero, and Claude.ai at 80. Alkon uses AI to synthesise cardiovascular research across multiple disciplines. Both demonstrate how accumulated expertise transforms technology from threat to strategic advantage.

"I announced that I'm going to university again. I've been on YouTube watching countless videos about different things... I would never have thought that I'd be using AI to the degree I'm doing at the moment." — Dr. Michael Best

Younger users often trust AI outputs uncritically or use technology to replace thinking. Professionals with decades of domain knowledge use these tools to augment evaluation, spotting errors novices miss. Best can assess whether AI-generated medical information makes physiological sense. Alkon can identify when chatbots conflate correlation with causation in health research.

This pattern contradicts narratives about cognitive decline and technology intimidation. The professionals maintaining cognitive vitality aren't those avoiding complexity but those engaging with intellectually demanding projects that require integrating new tools with existing wisdom.

Best's book project combines scientific rigour with public health advocacy. Alkon's eight-year research deep dive produced a comprehensive guide addressing knowledge gaps across multiple medical specialties. Both projects demanded learning curves that would intimidate many younger professionals—mastering reference management systems, evaluating conflicting research findings, distinguishing quality supplements from scams.

The common factor: intellectual challenge sustained rather than diminished their mental acuity. They didn't simplify their lives or retreat from complexity. They took on ambitious projects requiring sustained focus, critical evaluation, and synthesis across disciplines.

Practical Frameworks for Health Agency

Both interviews provide actionable approaches for taking control of your health while maintaining productive relationships with medical providers:

• Build your knowledge systematically, not reactively. Don't wait for symptoms to drive research. Alkon recommends understanding your metabolic health baseline—triglyceride/HDL ratio, C-reactive protein, insulin levels—before problems emerge. Best emphasises learning how your specific body processes medications through pharmacogenetic testing.
• Collect objective data doctors can't dispute. Temperature tracking for hormone function. Blood work from independent labs. Symptom journals with specific metrics. Documentation creates evidence bases that overcome dismissive responses.
• Develop source evaluation frameworks. Consumer Lab for supplement quality. Original research papers over secondary news coverage. Researchers with no pharmaceutical funding over industry-sponsored studies. Both emphasise distinguishing rigorous evidence from marketing disguised as science.
• Partner strategically with providers. Best's best gynaecologist listened, showed her ultrasound images, and adjusted treatment based on patient-presented research. Alkon's psychiatrist practices evidence-based medicine, making him an exception in her provider network. Seek practitioners who demonstrate intellectual humility and curiosity rather than defensive expertise.
• Use technology as cognitive extension, not replacement. AI excels at synthesising information across sources, identifying research papers, and generating initial frameworks. But humans with domain expertise must evaluate outputs, spot physiological impossibilities, and integrate findings with individual health contexts.

Energy and Wellbeing as Professional Assets

The connection between physical health and professional capability becomes more direct as we age. You cannot maintain high-level cognitive work while your body struggles with untreated sleep disruption, hormonal imbalance, chronic pain, or inflammatory conditions.

Alkon emphasizes this repeatedly:

"I started to feel like [my ADHD medications] weren't working in menopause... I would say my number and I would forget." 

Her memory returned when she addressed the underlying hormonal issue. Similarly, Best's patients reported regaining professional capability when chronic conditions that disrupted sleep and cognition were properly treated.

This isn't about optimising performance for its own sake. It's about maintaining the baseline physiological health that makes sustained intellectual work possible. Sleep quality affects memory consolidation and learning. Hormonal balance influences mood stability and executive function. Inflammatory markers predict cognitive decline years before symptoms appear.

Your decades of accumulated wisdom remain valuable only if you maintain the cognitive capacity to access and apply that knowledge. Professional longevity depends on physiological health—not as separate concern but as fundamental prerequisite for leveraging expertise.

The Broader Implications

These conversations reveal something beyond individual health advocacy. They demonstrate how professional wisdom developed over decades becomes increasingly valuable in an information-saturated environment where expertise matters more than ever.

Medical knowledge doubles every 73 days. Practitioners can't keep pace. But experienced professionals who've spent careers developing evaluative frameworks, recognising patterns, and integrating complex information across domains can navigate this complexity in ways younger practitioners cannot.

Dr. Best's 50 years of medical practice gave him the foundation to assess cannabis research quality at 74. Alkon's decades as an investigative science writer provided the skills to evaluate cardiovascular research despite no formal medical training. Both demonstrate how crystallised intelligence—accumulated wisdom and pattern recognition—enables capabilities that fluid intelligence alone cannot match.

This has direct implications for professional longevity. If cognitive vitality depends partly on taking agency over physiological health, and health agency requires accumulated expertise to navigate inadequate medical systems, then professional wisdom becomes self-reinforcing. Your decades of experience make you capable of maintaining the health that sustains your ability to leverage that experience.

What This Means for You

• You cannot outsource responsibility for your health to medical practitioners operating within systems that lag decades behind research. This isn't cynicism but realism based on institutional constraints that prevent doctors from providing the evidence-based care they want to deliver.
• Your professional experience—whatever your field—has developed evaluative capabilities transferable to health advocacy. The same skills that let you assess business research quality, spot flawed arguments, or integrate information across domains apply to navigating medical literature.
• The technology that intimidates many older professionals becomes strategic advantage when combined with accumulated wisdom. AI tools augment rather than replace expertise when used by professionals capable of critical evaluation.
• Intellectual challenge sustains cognitive vitality. Dr. Best at 80 and Amy Alkon at 61 demonstrate that taking on complex projects requiring sustained learning maintains mental acuity better than simplification or withdrawal from challenge.
• Most importantly: the knowledge gaps aren't your fault, but navigating them is your responsibility. Doctors won't tell you about treatment options they don't know exist. Medical systems won't proactively offer tests that could prevent problems they're designed to treat reactively.

Your accumulated professional intelligence makes you uniquely capable of the health advocacy that sustains your ability to continue leveraging that intelligence. This isn't burden but opportunity—to apply the evaluative frameworks you've spent decades developing to the most important project you'll ever work on: maintaining the cognitive vitality and physical wellbeing that makes everything else possible.
