We have to keep the body in good health; we have to take care of what we eat and drink, and what we do.

Exercise till the mind feels delight in reposing from the fatigue.

I have always believed exercise is a key not only to physical health but to peace of mind.

Exercise dissipates tension, and tension is the enemy of serenity. I found that I worked better and thought more clearly when I was in good physical condition, and so training became one of the inflexible disciplines of my life.

Well, a funny thing, there are three that I like all for the same reason, golf, fishing, and shooting, and I do because first, they take you into the fields. There is mild exercise, the kind that an older individual probably should have. And on top of it, it induces you to take at any one time 2 or 3 hours, if you can, where you are thinking of the bird or that ball or the wily trout. Now, to my mind it is a very healthful, beneficial kind of thing, and I do it whenever I get a chance, as you well know.

Exercise is bunk. If you are healthy, you don't need it: if you are sick you should not take it.
