The other pathway is a metabolic control enzyme known as AMPK, which evolved to respond to low energy levels. It has also been highly conserved among… - David A. Sinclair

And so, with all that on the table, what do I do? • I take 1 gram (1,000 mg) of NMN every morning, along with 1 gram of resveratrol (shaken into my homemade yogurt) and 1 gram of metformin.7 • I take a daily dose of vitamin D, vitamin K2, and 83 mg of aspirin. • I strive to keep my sugar, bread, and pasta intake as low as possible. I gave up desserts at age 40, though I do steal tastes. • I try to skip one meal a day or at least make it really small. My busy schedule almost always means that I miss lunch most days of the week. • Every few months, a phlebotomist comes to my home to draw my blood, which I have analyzed for dozens of biomarkers. When my levels of various markers are not optimal, I moderate them with food or exercise. • I try to take a lot of steps each day and walk upstairs, and I go to the gym

The Information Theory of Aging starts with the primordial survival circuit we inherited from our distant ancestors.

We also knew that many other health-promoting molecules, and chemical derivatives of them, are produced in abundance by stressed plants; we get resveratrol from grapes, aspirin from willow bark, metformin from lilacs, epigallocatechin gallate from green tea, quercetin from fruits, and allicin from garlic. This, we believe, is evidence of xenohormesis — the idea that stressed plants produce chemicals for themselves that tell their cells to hunker down and survive.
