Dumb. We do way too much in this country to fight the efforts of natural selection. You don't want to wear a seat belt? Fine. You don't want to wear a helmet? Great. Why should any of that be forced on us? Let natural selection run it's course!
I could not agree more. As long as people aren't hurting others, I don't give a flying f*ck what they do with their lives.
Wear a helmet or don't, strap on a seatbelt or don't, whatever... the consequences are on you, and the government shouldn't have a say in it. Period.
