Here are some of my favourite quotations on health by some famous folks:

Arnold Schwarzenegger

Be careful about reading health books. You may die of a misprint.
Mark Twain

The secret of health for both mind and body is not to mourn for the past, nor to worry about the future, but to live the present moment wisely and earnestly.
Buddha

Health nuts are going to feel stupid someday, lying in hospitals dying of nothing.
Redd Foxx
