Aging: Health, Safety, Community

Quick Takes

🧩 The longevity movement has a blind spot. Strength training, protein, sleep, glucose management, VO2 max — all of it matters and I recommend it to all my patients. But it addresses only the biological engine. Between mitochondrial health and actually living where you choose into your 80s and 90s, there is a gap. Let’s start talking about it.

💃 Fitness and reserve are not the same thing. Fitness is your current capacity. Reserve is the gap between your current capacity and the threshold below which you cannot live independently. The surgery you might need at 78 requires an absolute amount of muscle, nutritional reserve, and physiological resilience — and either you have it or you don't. There is a 90-second test that helps predict whether your next hospitalization will end your independent life. It's called the Timed Up and Go test — and your number matters.

🏠 Home modifications are both common sense and research-proven. The evidence supporting home safety modifications — grab bars, lighting, cleared pathways, single-level living — for reducing falls and delaying institutionalization is as solid as the evidence for exercise. And yet almost no one does a structured home audit before something goes wrong. The home may be seen as a type of

💊 Medication review every six months keeps people out of nursing homes. This is one of the most consistently proven interventions in the geriatrics literature — and it is not often practiced. The average older adult on five or more medications faces exponentially increasing risks of falls, cognitive impairment, and hospitalizations from drug interactions alone. Sedatives cause falls. Bladder medications impair cognition. Blood pressure medications may cause dangerous drops upon standing. A thorough medication review — not a refill appointment, a real review — changes outcomes. Ask for one. Bring your supplement list too. Work with your pharmacist, your PCP, and a functional medicine physician who is interested in coming up with creative alternatives to pills.

🤝 There is rarely full independence at 85. There is only degrees of dependence you planned for. And interdependence from your community. The most sophisticated and meaningful aging strategy I have ever encountered was not a supplement protocol or a biological age intervention. It was a community of women who developed a tradition of visiting older friends — people who could not reciprocate. As they themselves age, their younger friends show up. Nobody keeps score. They have built a culture of showing up.

🌱 The option to live on your own terms at 85 is being built right now, in the relationships and communities you are either cultivating or neglecting.

Favorite Finds

• 🤲 Handexer Dynamometer — around $39 Grip strength is one of the most powerful predictors of surgical outcomes, cognitive decline, cardiovascular disease, and whether you recover your independence after a major health event. Buy one. Measure both hands. Look up age and sex norms. Know your number. This is the kind of information that changes behavior.

• 🧠 BrainHQ — brainhq.com The most evidence-backed consumer cognitive training platform available. The ACTIVE study — the largest brain training trial to date — found that its speed-of-processing training was associated with a 29–48% reduction in dementia risk over a decade of follow-up. It also gives you age-matched peer comparisons across multiple cognitive domains so you can track your trajectory over time.

• 📋 Aging in Community: A Self-Assessment and Action Workbook — new this week 150 pages. 5 clinical domains. Dozens of tracking tables and checklists with specific language to use with your physician, your PT, your pharmacist, your elder law attorney, and your financial advisor. Everything the longevity conversation misses — measured, tracked, and acted on. Available at launch price ($37) until July 9th.

• 🎓 Course in development — tell me what you want! I am considering building a course around this framework with a colleague who coordinates care and navigates the post-acute system on the ground every day. Before I do, I want to know what would actually help you.

The Three Eras of Aging Well — And Why Most of Us Are Living in the Wrong One

We have rethought aging three times. The first era gave us grab bars and walkable neighborhoods. The second gave us mitochondria and the Centenarian Decathlon. The third brings these together with connection, purpose, community, to create the deliberate infrastructure of a life that holds together when something goes wrong.
