If you don't care if people live or die then why would you want them to wear a seat belt. You seem to contradict yourself all in one breath.
NO not OK with the deletion of PE. Dad killed in car wreck when I was 6 wearing seat belt. I had a pretty bad one in highschool also wearing seatbelt and not a scratch, but am certain would have gone through windshield if unbelted. ALL research and ALL evidence PROVES that seatbelts SAVE lives, so your argument there is just, well I really hate to use the term, but, stupid.
As to smoking, the biggest problem I have there is that it isn't fatal quickly or reliably enough. If you have paid ANY attention to my posts over the last couple of years, you know that I am mostly a misanthrope and think that there are way too many people on this little blue sphere and so don't really care if folks commit suicide, just wish they would use more reliable means than tobacco use. If it worked more reliably and faster, it would be a good tool to help raise the collective IQ. Actually goes for ADULTS and seat belts too.
