Steve I didn't know that story about Frederik Pohl-thank you for posting it, fascinating. Also, they weren't all yuppies at the FL teens & twenties cryonicist conference, there were representatives from all sorts of backgrounds/classes. Personally my motivation in signing up for cryonics is that I think the amount of knowledge that we have to learn about the Universe pales in comparison to my short natural lifespan, that keeps me in awe-as I currently learn all that I can, and all the new things I realize I don't know. That said, I'm perfectly happy with my own life, with my family, friends and community work and if I get more time, an "extreme lifespan" to see what is out there in the billions of light years of space, if I get more time to help end inequality if it still exists--or to move on to other goals, then so be it-I got lucky that cryonics worked ;-)
