Kurt, that is a good point. I heard of Cryonics on T.V. when a teen--but didn't take it seriously till I was told by a Doctor during a high-risk pregnancy at age 21, that I could die. I researched cryonics a lot more and learned it was more feasible than the generally media made it out to be.
I think when people grow a little bit older perhaps they are confronted with their mortality upfront in a way that makes them want to do something about it. Sure we all would not walk in front of a bus, but not all do CR or cryonics, or became 300 members (our best 'chances' right now for longer and a very long life).
I really don't know why families would be hostile to these ideas--it is indeed interesting to me to see how my children carry into their adulthood these ideas they see as natural now. The have a healthy dose of volunteerism, and activism under their belts as well-- so I'll continue on with them as my little experiments
I included a chapter about China in the future in my book, hoping that it might someday appeal to an Asian market-- I'd sure love some Immortalist that speaks Chinese , or has familiarity with Chinese culture, to read my book and let me know their ideas of how it may go over in that country. I'd sure have to sell a lot more likely before I could be translated however-- but I did write my book for all '21st Century (Earth) Kids'
