““I think it is effective to constrict your anus 100 times, dent your navel 100 times in succession everyday. You can do so at a boring meeting or in a subway without being noticed for you to do so. I have known 70 year old man who has practiced it for 20 years. As a result, he has good complexion and has grown 20 years younger. His eyes sparkle. He is full of vigor, happiness, and joy. He has neither complained nor born a grudge under any circumstance.””
