While the average life expectancy in the United States is 78 years, the leading causes of death are typically related to health. Heart disease, cancer, stroke and diabetes are some of the most typical causes. Accidents do cause a large portion of deaths, however. Most people are afraid of recreational activities, such as base jumping and hang gliding, with good reason. Though most people who partake in these activities do not die, base jumping is the most dangerous recreational activity.

In the end, even doing ordinary things can cause death. One in 100,000 will die in the middle of a dance party. Even playing board games gives you a 1 in 100 million chance of death, and the same goes for computer games. No matter what you are doing, there is some risk involved. No matter what you choose to do, your chances of dying in a given year double every eight years.
