Hey I look after a lot of people who have sports related injuries at the hospital, broken bones cost a lot to fix.
Using your logic we should only allow people to use exercise bikes while wearing protective clothing, no contact sports or anything outdoors.
I don't really want to get in the middle of this, but the logic behind that does not apply to sports examples. In sports people are WILLINGLY PARTICIPATING. If they get hurt, that happens as it's part of the game. There are known risks, and they accept that.
However, if an athlete wearing full pads tackles you at full speed while you are wandering down the sidewalk, you probably wouldn't like that. What if you get tackled 3-5 times a day? Is that their right to do that because it's their choice?
Personally, I don't care who smokes or doesn't as long as it doesn't affect me. People obviously know the risks of smoking and accept it, so more power to them. What irritates me more is when people use absolutely ridiculous argument tactics that make no sense. I realize there aren't really any solid arguments behind smoking in particular other than "because I like it" but come on, at least try. Making wild exaggerations doesn't help your case.
