Question

2．There is no second chance…there is no chance of making mistakes．"
 That's why Dr．Omer Mei-Dan and others who enjoyed base-jumping and wingsuit（翼装） flying were sad but not surprised by the recent deaths of three extreme sports enthusiasts．
Mark Sutton，the English parachutist（跳伞者），died on August 14 in Switzerland when he flew into a rocky ridge（山脊） in a wingsuit．Not even a week afterward，Mario Richard，a Canadian base-jumper，died in Italy during a wingsuit flight，when he"apparently failed to clear a rock by three meters．"And most recently，Hungarian wingsuit flyer Victor Kovats died in Tianmen Mountain National Forest Park in Zhangjiajie on Oct.9 during a practice flight ahead of the World Championships．
According to Mei-Dan，six to seven percent of the 3，000 or so base-jumpers who use wingsuits or parachutes die each year-a huge number when you consider the most dangerous job in America，logging which has an annual death rate well under one percent of the workers．
Base-jumpers and wingsuit flyers are experienced．They have hundreds of practice before trying to fly from buildings，cliffs and towers．The same goes for those who drop from helicopters above mountains and valleys and then use their wingsuits to try to whiz by（飞速掠过） as close as possible to the rocks and ridges below．
Among the dangers，said Mei-Dan，is the temptation to"push the envelope"：To try to get close to a rock wall，for example，than anyone else．"When you push the envelope and you can not have any error at all，or you have to pay for it with your life．"
So why do it？The experience of flying toward the ground in a wingsuit is almost indescribable．"It's something that you really have to try to understand-what type of feeling you get when you're free falling next to a cliff，"Mei-Dan said．
