What do you do if you find four $100 bills lying on the sidewalk?
Good point. But I was trying to be brief and not write a dissertation.
What I mean is that what many people find "fun" can shorten your life. Whether it's bungee-jumping, car racing, skydiving, playing video games!, watching the telly from the couch, etc., ad infinitum all have certain risks.
I'd imagine that bungee-jumping is FAR riskier than playing video games. If that bungee breaks, it's all over. Some people like to play video games. Some people like to bungee-jump. It's all a personal matter, and a matter of an individual personally managing risk. The government has no business in deciding here.
A long life spent having no fun is no life at all.
