Prevent Aging by Doing

The way an individual ages, the way he dies, is to give up his power of observation and his power of decision, and acts on the basis that he cannot do as much as he used to be able to do, he can't stand as much as he used to be able to stand. And he attributes this to advancing age. He never attributes it to being able to stand less."

“The source of advancing age is being able to stand less. Advancing age is not the cause of being able to stand less."

“In other words, aging is caused by a lessening ability to confront action. That is all. It's not because the person can't, but he merely ages because he believes he can't.”
