I agree, as to GP, I'd play the Russian roulette with my own life, but not with what is quite possibly every intelligent life in the universe (aliens are not known to exist). I would also require that the credibility of actually carrying out the task of preventing aging and curing all diseases is actually not some sort of trick and is going to happen in a reasonable way. Probably somewhere pretty close to P(1-epsilon) would be required.
