笑瑜伽：在公园里用笑声做运动
Every morning, people gather in a park in India. They come for laughter yoga. It is a fun kind of exercise. You do not need a joke. You just start laughing.
A leader shows the group what to do. She says, 'Ho ho, ha ha ha.' Everyone follows her. Soon the fake laugh becomes real. Your body does not know it started as a game. You feel warm and light.
