"Of all the exercises, I should say that Tai Chi is the best. It can ward off disease, banish worry and tension, bring improved physical health and prolong life. It is a good hobby for your whole life, the older you are, the better. It is suitable for everyone - the weak, the sick, the aged, children, the disabled and blind. It is also an economical exercise. As long as one has three square feet of space, one can take a trip to paradise and stay there to enjoy life for thirty minutes without spending a single cent".
