 And I've likened it to some things I learned about genetics, which is to say that when you're exposed long enough to sunlight, you only got so many panes of glass between you and cancer. And when you go and get a really good sunburn, you break some of those panes of glass. And you go and expose yourself to toxic chemicals, you break some of those panes of glass. You can't recover from them. You can stretch it out as long as possible.
