Know what else is good for you?
I've come to realise that sometimes things that started out being a problem turn out to be a necessity. Maybe even the worse things are like that for example an abusive relationship or a dead end job. In the end they come to define us and we may feel we're nothing without them.
On a lighter note check this out.
"Low background levels of radiation seem to be good for you. The evidence that the "linear extrapolation to zero" is wrong, accumulated by Bernard L. Cohen, an emeritus professor of physics at the University of Pittsburgh, comes from many sources. Bad for you in large doses, radiation does some good in small doses. It seems to keep the DNA repair mechanisms in good working order. The same principle is observed with alcohol, and a number of other poisons. Very heavy drinking will kill you, but a glass of wine a day is a tonic.
With radiation, nonetheless, the operative principle has been "zero tolerance," permitting environmentalists not just to stop nuclear tests, but to demonize nuclear power and to stymie the disposal of nuclear waste as well—with little discussion of the evidence. As the recent energy problems on the West Coast suggest, we are going to have to start building nuclear power plants again. Meanwhile, Art ruefully points out, the hormesis data show that Oregon is not a particularly good place to live. Its background radiation levels are below the national average, and its cancer rates are above average. There's less cancer risk in Denver, where the background radiation levels are much higher. That inverse relationship holds all over the country. "
