Just began watching. Having studied evolutionary biology taught by the #1 scientist in the field, ultimately, as David admits, anti aging is about minimizing the cycles in the mitochondria by various means, and the one we are most in control of, and at the least cost is reducing meals. Fasting, which most fat Americans never do, provides huge payoffs. And the more often is better. One thing we can all do is eat only one meal per day. And if you don’t have it, due to whatever busyness, is even better, of course. Folks, stay busy. And a bit hungry, if you want to live longer. Cheers 🥂
