Heart, brain, gut and mouth — the systems that tend to fail first. These are the health experiments I run on myself at 71: what I test, what I changed, and what the research actually says, with the numbers in public.
A headline says weight loss drugs are driving a 50% jump in divorce. I lost 168 pounds and stayed married, so I read the actual study. The part everyone misses: the relationships at risk are themselves one of the best-evidenced longevity interventions there is.
TruDiagnostic sent me the TruAge + TruHealth kit. One finger prick, 180+ biomarkers, eleven separate organ ages, and a telomere estimate that will second-guess everything I have been taking. Then I interview the founder.
I switched off plastic coffee pods and thought the job was done. Six months later I realised the water was still running through plastic tubing and a plastic basket. Here is the glass setup I use now, and why I think it is worth it even though the science is not settled.
I used to watch the sunrise from the dock every morning to set my circadian rhythm, and then the traveling took the habit away without me noticing. Now I am rebuilding it as a two-mile walk — and starting a daily series recorded while I walk.
Longevity escape velocity is the point where medicine adds more than a year of life for every year that passes. Here is what Aubrey de Grey actually proposed, what the mouse studies show so far, and why the timing matters more at 71.
Hot water plus plastic plus every single morning is a bad combination, and my old brewer still had plastic in it. Here is the glass, steel and wood setup that replaced it, what the research on microplastics actually shows, and the one trade-off nobody selling a metal filter will mention.
Somebody asked me whether mahjong is good for seniors and I went looking expecting folklore. Instead I found randomized trials. Here is what the research actually supports — and the one ingredient doing most of the work.
When I say I plan to live to 200, most people answer that they would not want to work that long. That answer says more than they realize — and it explains why Bitcoiners and longevity people keep turning out to be the same person.
Glacier water is not mineral rich — it is closer to distilled. What is actually in the meltwater at Dawes Glacier, why it tastes the way it does, what nobody puts on the label, and whether I would drink it again.
I had my whole genome sequenced at 71. No monogenic disease variants, two favorable FOXO3 longevity variants, and three vitamin predictions I could check against my own published blood work. Here is what it found, and what I am deliberately not publishing.
I’m 71 and aiming for 200. My biggest longevity mistake has been trying to do it alone. Here’s why I’m building a group for accountability and shared learning.
For adults over 70 the median overnight HRV is about 36 milliseconds. Mine went from 48 in April to a 75 baseline in August at 71 — here is what the four-month chart actually shows, and what moved it.
The man who coined longevity escape velocity said yes to an interview. I get one shot at it, so tell me what you would ask him.
I sat in a cruise ship salt therapy room and felt nothing — because the halogenerator was switched off. Here is what happened when I started it, and the 10-minute limit posted on the door that changes the whole picture.
A cruise ship spa room built around a large amethyst crystal, sold as a conduit for natural healing energy. I sat in it, paid attention, and felt warm and quiet and nothing else. Here is the honest null result.
A major JAMA study of 131,821 people over 43 years found the top caffeinated-coffee drinkers had an 18% lower dementia risk — with a sweet spot at 2-3 cups a day. Decaf showed no benefit.
Sixteen grams of protein for eighty-two calories, 370% of your B12, and a sodium load worth watching. What Alaskan king crab actually does for an aging body — and whether it was worth a hundred dollars.
An Alaska cruise hits four longevity levers harder than most of the gadgets in my house — cold, steps, awe, and connection. Here is my protocol for the trip, and an honest list of the ways a cruise works against you.
A Google-backed team just reversed a form of aging damage long considered permanent — cutting it 55-70% in aged human tissue. A real age reversal breakthrough, and what it actually means.
The short version: I switched to aluminum-free deodorant. Most antiperspirants use aluminum compounds to plug sweat glands, and daily use adds up over decades. The science isn’t settled: large reviews haven’t found a definite link to breast cancer or brain disease, but some researchers urge caution. For me, avoiding a daily exposure I don’t need…
