Lecture: Atmasvasth - How to Design Your Healthspan
A 24 1/2 minutes lecture that discusses what you can do with primary and secondary prevention to improve your healthspan
I was to deliver this lecture around this time today, but due to unforeseen circumstances that did not happen.
I recorded the lecture anyway, a 24 1/2 minutes discussion about what we can do to improve our healthspan... from primary to secondary prevention and the levers that matter the most...from physical activity to testing.
The gist, if you're not going to watch all of it:
We're almost all going to live long now — the only real question is whether those years are healthy ones. Genes set maybe 20–25% of it; the rest you design yourself, through what you do every day (primary prevention) and a small, sensible set of tests (secondary prevention). And the single biggest lever isn't anything fancy or expensive — it's physical activity, where even the first five minutes a day make the biggest difference.
What I cover:
0:00 Why "design" your healthspan, and what's changed since December
2:07 What healthspan actually is — and the lifespan-vs-healthspan picture
3:27 Genes vs what you design; where "Atmasvasth" came from
4:20 What we control — primary vs secondary prevention
5:42 The three principles, and the relative importance of each lever
7:42 Physical activity — the #1 lever, and the "5-minute pill"
10:09 Sensible eating, salt and sugar
11:47 Sleep — 6–8 hours, naps, caffeine, the room
12:58 The exposome — air, heat, noise, road safety
15:19 Senses, medications, supplements, vaccines, and not falling
17:30 Secondary prevention — what actually kills us, and the few tests worth doing
22:10 Your PREVENT score — a floor, not a clean bill of health
23:03 Designing your healthspan — pulling it together
Going deeper — the new pieces this talk leans on:
- The 5-minute pill
- What actually kills us (GBD 2023)
- Sleep at the bottom edge of normal
- Don't drive at night on highways
- PREVENT over QRISK3
