True, you can't escape all bad things, but you can certainly make choices that are better and limit your risk.
Complaining about fluoride in the water, for example, is a bad excuse for drinking Coke, which not only has fluoridated water, but TONS of sugar and caffeine (or Aspartame, if you're drinking Diet Coke)
Kind of a lame excuse, like "Well, we all have to die somehow, so I'm going to snort this cocaine over here..."
Yeah, we're all going to die, but why hastily bring about your own death?
