The table should be interpreted to mean that the activity listed lowers, on average, the U.S. life expectancy by the stated number of days or that engaging in the listed activity lowers your life expectancy by the given number of days. For example, the presence of suicide in the U.S. lowers the average life expectancy by 95 days. Being a grade school dropout, on average, lowers a person's life expectancy by 800 days.
Note that both the Nuclear Regulatory Commission (NRC) and the anti-nuclear organization Union of Concerned Scientists (UCS) both estimate the risk from nuclear power to be much lower than many other activities in our lives. Compare the risk estimates for nuclear power to that given for hydroelectric power!
