题目内容：

I've been working as a professional clown(小丑)for nearly two years. Before that, I was an actor for nine years. I was never famous, but I was quite successful! I changed jobs because I wanted to do more in life than make people laugh. What if I could help people, too?

As a clown, I try to encourage sick children in hospital to laugh and smile. When you laugh, your mind and body relax. Clearly, people who laugh more don't have as many colds or other problems! Children who laugh a lot often get better results in their studies, too.

It isn't an easy job. Not all sick children get better, and sometimes I come home and cry. But I always go back to work the next day with my red nose on. l don't earn much money as a clown, but I feel very lucky to work with such brave and wonderful patients.

I became a laughter yoga(瑜伽)teacher more than two years ago. Before that, I was a dentist! My job was very difficult, and I used to feel fed up. Now I still improve people's health, but everything else is completely different. Everyone has fun in a laughter yoga class, including the teacher!

No, laughter isn't "magic". It doesn't prevent all illness, keep you young, or make you beautiful. But did you know that it's an excellent kind of exercise? You move your whole body when you laugh!

Sometimes I work with famous people. It's true that being rich can be stressful! Some famous people can be unpleasant at times, but I try to change their bad feelings. Laughter is excellent for people like musicians, artists and writers, because it helps people to be more creative.
