Part of this is that the human brain doesn't process information as quickly as it could. This is dangerous when people drive late at night or early in the morning, because they cannot react quickly enough to other drivers and traffic lights. By decreasing the time dedicated to sleep by just an hour and a half, daytime alertness is reduced by 32% (Function, par. 4). It becomes difficult to concentrate and people become confused more easily due to less and less sleep. The symptoms of sleep deprivation are extremely close to those of a drunk person. Someone who is drunk should not, or at least should not, go out and drive, perform an operation on someone, or fly a plane. So why do we have jobs like these? The average American should be more educated about sleep deprivation, so no problems and accidents
