That's how I'd like to think that they'd go about it. I'd be interested in learning the details. Say for example that younger people tend to be able to go without for a longer period than older people. I don't know if that's true, but if so you could prolong the lives of older people now but then get to the younger folks later, but not necessarily vice versa.
