You know what I was talking about with the burger analogy. Excuuuuse me for not getting my bacteria right.
Driving already has GOVERMENT REGULATIONS, or did you forget that? Would you prefer that everyone just drove the way they wanted to?
Everything else you mention only affects ONE person: the person that is consuming the read meat, the person that is eating too much or not enough, and so on. You can't spread your heart attack to other people by eating steaks. When you smoke, your habit is affecting everyone around you. That's the difference between "public" and "private."
Nice stereo-typical American attitude, though, putting your "god-given" rights before your responsibilities.
