How long the beast has to be chained up.

Being immortal would inevitably be the worst thing in the world. My reasoning is that if you're around forever then you will do everything eventually. It'd be awesome for a while but that's only temporary and since immortality is infinite then you got a whole lotta suck coming your way. You would literally do everything. Do you know how much stuff sucks? Most of it, that's how much. You're at the mercy of everything because no matter what you do everything is gonna happen. There is no way you could possibly not get herpes. It's gonna happen. Enjoy that for eternity, Prometheus. Ever been on swing set and go over the bar then get turned inside out? No? Just wait. It's gonna happen. Probably twice.

You're gonna get around too. When people travel they usually go to awesome places and are all like "Fuck yeah, Honey, get the camera and we're going to pretend we're holding up the leaning tower of Pisa because we're fucking assholes". Since you're going to live forever and do everything then you'll probably also travel everywhere as well. Nobody would ever want to go to the desert. There's a reason the word "deserted" is what it is. Don't wanna go? Too bad. You're somehow going to get there whether you want to or not. You're gonna walk around and get lost and tired. You'll lay down and give up eventually then sand is gonna blow over and bury you and you'll be there for a bazillion years only to emerge when the dune blows past you. Then you'll stand up and walk around, still lost, only to get buried again and then it just perpetuates and you're the sandiest son of a bitch in the world for the rest of your life. Oh, and you're immortal so that's for a fucking while too.

Living forever is like sharing a prison cell with geography and you're the bitch.
