coming out of cell phones，it isn't really safe to sleep，drink or talk.
Last week the entire Metro system in Washmgton had to close down because some- one might be blown onto the tracks during a hurricane.This week children in Washing- ton were not allowed to go to school for a whole day because streets were blocked by fallen trees and power 1ines，and traffic lights at some intersections weren't working.A previous generation might have walked around the fallen trees and looked both ways be- fore crossing the street，but the children of this generation clearly live in a much more dangerous world，and we need to protect them.
After Sept.11，2001，thousands of people swore off airplanes and began driving cars.In fact，the odds of being killed in a terrorist incident in 2002 were one in 9 mil- lion.In that same year，the odds of dying in a traffic accident were about one in 7,000.
By taking the precaution of not flying，many people died.
There are some clear psychological explanations for some of this.It's a fact that people fear man-made disasters(terrorism)far more than they fear natural disasters (hurricanes)，and they are more afraid of things they do not control，which is why driv- ing a car does feel safer than flying in an airplane.Also，although I have no proof，I'll hazard a guess that people are disproportionately frightened by things they read about in the newspaper.By contrast，they are disproportionately willing to discount the evidence
of their own experience.If you look around your neighborhood，you’1l notice that the
water is clean—which it wouldn't necessarily have been 100 years ago—and that the food isn’t rotten or stale.
Life is far safer for the average American than it ever has tor j ust about anyboay at any other time in human history—and maybe that explains the ludicrous precautions that city officials and federal bureaucrats and everyone else feels obligated to take nowadavs to satisfy the public's demands.Now that we'Ve eliminated most of the things that
the human race once feared，we've just invented new ones to replace them.
