A few months ago I was talking to my friend Dan Pardi (founder of Human OS) at the 111 Minna 20th anniversary party. Despite the loud techno music, Dan and I got into a conversation about health, nutrition, and supplements (as we usually do). Dan told me about some interesting research on the compound fisetin (found in many foods, but especially high in strawberries). Just a few high doses of fistetin, fed to mice, improved health and significantly extended lifespan, even when given to older (middle-aged) animals.
