If you leave your arms out, they float free in zero gravity, often giving a sleeping astronaut the look of a funny balled(芭蕾)dancer. "I'm an inside guy，" Mike Hopkins says, who returned from a six－month tour on the International Space Station. "I like to be wrapped up."

　　On the station, the ordinary becomes strange. The exercise bike for the American astronauts has no handlebars. It also has no seat. With no gravity, it's just as easy to pedal violently. You can watch a movie while you pedal by floating a microcomputer anywhere you want. But station residents have to be careful about staying in one place too long. Without gravity to help circulate air, the carbon dioxide you exhale(呼气) has a tendency to form an invisible(隐形的)cloud around you head. You can end up with what astronauts call a carbon－dioxide headache.
