Longevity and the nature vs nurture debate: which is more important, heredity or lifestyle? Dr Peter Attia and I agree that exercise is key!

I eat nutritious, healthy home-cooked food, but I suspect that my good health might also owe something to a specific vitamin regime.

I bought my first pair of New Balance shoes in 1965. Since then, I ran several marathons in NB shoes, and I still wear them today.

I like good food. And antioxidants and a few supplements and vitamins have been part of my health-care routine for decades.
