Wouldn't that be lovely?

I wish that the immediate reaction by most people to such a thing wasn't something preposterous like "death is natural." Yeah? So? We are not beaten in the heads with rubber mallets every day at noon. If aliens showed up and proposed that we adopt the rubber-mallet system for no benefit, we'd call them crazy.[1] Yet death, which is completely real, is treated as something not even worth attempting to cure (although we sure love trying to prevent it when it's basically too late!)
