Some people say that laughter is the best medicine. Scientists are beginning to agree with this. They are studying laughter seriously(认真地，严肃地)and finding it is really good for us.
So what happens when we laugh? We use fifteen different muscles(肌肉)in our face,and laughing is good for every organ(器官)in our body. When we laugh, we breathe quickly and exercise the face，shoulders(肩膀)，and chest. Our blood pressure(压力)goes down，and our circulation gets better. Our heart beat is lower and our brain makes a natural painkiller (止痛药) called a beta-endorphin.
Every minute we laugh is the same as forty-five minutes of relaxation. Many doctors around the world believe that laughter helps us get better when we are sick.
Of course，there are many kinds of laughter. We may change the way we laugh in different situations. But we all have a laugh that is special to us. How do you usually laugh?
