I don't think that I would live much differently than I do now. I would try to learn new things all the time, otherwise I would be very bored.
Well, yeah, they could TRY to keep you in jail. But you could break out because they couldn't stop you (if you couldn't feel pain and nothing could harm you, as would be implied by doing all those drugs). Think about it. You'd just wait until the guards brought you food, waylay them, and take off with their keys. It wouldn't matter if they shot you... you'd be invincible. Nothing could hold you down.ZAP
I'd go on a tour of the European red-light districts, maybe Southeast Asia, too... and I'd sell most of my internal organs on the black market... oooh, and I'd go swimming in the Gulf of Mexico and drown myself so I can look for old ships and treasure at the bottom... plus, I'd also like to walk on the moon in a spacesuit without an oxygen tank... and while they're at it, NASA can send me to the outer reaches of the solar system, since there's no limit to how old I can be... and then I'd veer my ship into a black hole to see what's really on the other side... ahhh the possibilities...
Well, what DOWNY presupposed what that you couldn't feel pain... otherwise there would be no point in doing all those drugs because you would be comatose, although alive. So his supposition, in my opinion, changed the playing rules.ZAP
