The difference is that if some1 is smoking or drinking, fugging up their lungs and livers then its their lungs and livers to waste.
I think its a completely different thing if some1 has a transplant and recieves some1 else’s organs. I would say it becomes their duty then to protect those organs that were given to them instead of some1 else.
If George Best survives this he’ll drink himself and his new liver into oblivion within a few years anyways.
