Markos,
I hear you and I understnad your reasoning. Smoking has been banned in many public places because it does affect other people. If you get lung cancer, it is not something the hospitals have to treat unless you have insurance.
I don't thinks guns should be on your list because it may actually save you from going to the hospital. Just be sure to kill the bad guy to save the expense of treating him, not to mention yourself from a civil suit (unless it comes form his family).
As for skydiving, the only expense comes from having the road kill crew scrape you up. No much chance of needing treatment for that one!
Same for flying a plane, most plane crashes don't require medical treatment either. Often times, you get free cremation thrown in. (Here are your husband's ashes... at least we think they were your husbands. Sorry... I know... not funny with the recent plane crashes).
Driving would probably be a better example since auto accidents kill so many people every year. The problem is that driving is pretty much a necessity most of the time.
As for McDonald's Big Macs, they should be outlawed. We have such a rediculous rate of obesity in the US. We are a nation of PIGS!!! I was reading something on
MSN the other day and our national obesity rates are over 22%. That only covers obese people. I'd hate to guess how many are over weight but not considered obese yet. I'm not trying to turn anyone into an anorexic but obesity leads to a whole slew of health problems. How about heart disease for one, or diabetes. Don't forget the psychological damage obese people go through in life. BAN BIG MACS NOW!!!
