I'd actually do it. Though, if someone shoots you, you still live? If so, I'd be the most wanted guy in the world just for the sake of trolling the world.
this is realy a polemic question,but i wouldnt like to live that much,we were born in this age becuz it was our destiny,and i dont think someone sould live more than it is expected to him,like what would it be if cavemans were still alive??they would fit properly in the society,so do i would not like to live in the future with my old way of thinking
If you want to see a film about this, watch "In Time". It's when humans have clocks on their arms of the count down till their death. The global currency is time and you can get more by working and gambling etc.
If you were the only one: nope, I wouldn't. I would hate to see all my friends and family die, make new friends, have them die, and that cycle repeats.
You'd become depressed and have no way to end it in peace.
Even if you didn't age, you would have to find a way to fend off diseases, regrow limbs, combat viruses, and heal any internal wounds. There's also the problem of you feeling pain and dying from your entire body being destroyed.
