Heh heh, if you want to kill yourself by smoking or over-drinking please do it without affecting others...
Unfortunately it is very difficult to achieve this without placing a burden on the hospital system.
Then again, if you over-eat or probably participate in a number of activities you can end up in the same situation, so I guess it is unfair to target the burden on the hospital system. That's why we pay taxes.
Anyway, I don't think I would like anyone smoking in the shed, they can smoke outside.
