I attempted suicide last week, but for whatever reason (not ready, I guess?) I stopped partway through. That, combined with my interest in attempting to become a hitman (hasn't worked so far, go figure) made me think about assisted suicide. It's really a win-win if both people are serious, right? There is no risk of failure, or brain damage or anything like that, because the person doing the work is going to make sure… unless they pussy out, I guess, but you're no worse off than you were in that case.
I thought about this quite a bit, and it would be excellent for both people - think about it: You gather all your identification, drive to a secluded spot, pre-dig a grave, do the work, hude the body, sell the completely valid identification. The person doing the work gets paid even if the person dying has no money, and the person dying can't chicken out, and has no risk of accidental retardation.
