Ray Kurzweil: I take 150 pills, which is maybe 70 or 80 different things; there's a different story with each one. Although people find that a very aggressive program, it's actually very conservative, because everything I do actually has a lot of evidence. Aging's not one thing; it's many different things.
1) Coenzyme Q10 is very important, particularly at my age, as an antioxidant.
2) Phosphatidylcholine addresses all by itself a major aging process because that substance depletes from your cell membrane and that's why the skin in an elderly person loses suppleness and your organs don't work very well.
3) I'd throw in Vitamin D. It's very important—maybe the most important vitamin to take. There's tremendous amount of research and a consensus that that really does help prevent cancer and other diseases.
