"A man over forty is either a fool or a physician"

In the spirit of Montaigne, that "a man over forty is either a fool or a physician," here are my heath tips:
Exercise matters, in the sense that some is much more important than none, but a lot provides not much more benefit than some.
Don't eat too many carbs, eat meat, fish, and greens, drink a glass of wine with dinner, and walk when you can. You won't live forever, but you will be happier and less of a health bore than the people who try.
