Exercise

I found many Americans do exercise everywhere at any time. In China, most people do exercise in a gym any time. Or many people exercise in the morning and in the evening outdoors. And I have never seen Chinese exercise at noon, but in America I see many people jogging at noon outdoors. It's really different from China. If someone is jogging at noon outdoors, people must feel very strange and everybody looks at him. But in America nobody cares. I feel Americans really like exercise, and do very much. But I think that's good for health and it's always better than never doing exercise.
