"I have always believed that exercise is the key not only to physical health but to peace of mind."
  — Long Walk To Freedom

Exercise makes the body strong, the vital dynamic and the mind peaceful. Your exercise regime in prison inspired young and old alike and preserved your body for the great tasks which lay ahead. You started life afresh at the age of seventy-one when you were released from prison. Now, in your eightieth year, you abound with youthful energy and dynamism. Dear President, how we all wish to emulate you!
