Physical fitness is not only one of the most important keys to a healthy body, it is the basis of dynamic and creative intellectual activity.

It is health that is real wealth and not pieces of gold and silver.

Take care of your body. It's the only place you have to live.

Leave all the afternoon for exercise and recreation, which are as necessary as reading. I will rather say more necessary because health is worth more than learning.

Walking is the best possible exercise. Habituate yourself to walk very fast.
