I like the way you think. But if exanguination is definitely your choice of exit, I would take the aspirin at extremely high doses over the next few days b4 you make the jump. The antiplatelet effect of NSAIDS is effective, but it takes a few days to reach its maximal effect (from what I understand). More importantly, imo, slowly bleeding to death is probably not a comfortable way to die. I would suggest you find a higher point from which to make your jump, and you will not have to concern yourself with the prospect of surviving the initial impact of your fall.
