Ordinary people who don't want to miss out on life in the future.
I'm now 65 and I think life is far too short. I have no desire to die. If the time ever came when I was fed up with life then I wouldn't go in for suspension. If it becomes possible to bring us back then we would be revived as young and active people and not as 80 or 100 year-olds.
I am a big fan of gadgets and I feel that I am missing out on the technologies that are going to be around in the future. It's going to be mind blowing what sort of stuff you'll be able to do in the future, thanks to developments in computers and electronics, and to be part of the new technology as well, in cryonics, I think is an opportunity not to be missed.

I don't particularly like the idea of being dead anyway, and with cryonics there's a small chance of death not being the end. There are still an awful lot of things I would love to do, and future technology could improve our learning capabilities. If I came back I would like to learn more about science and learn how to speak more languages.
The most famous cryonics patient was a baseball great who played for the Boston Red Sox in the 1940s. When he died In July 2002, the 83 year-old Williams was first treated in Florida and then flown to Alcor HQ, where his body is kept frozen. His daughter threatened, but later dropped, legal proceedings against the controversial treatment.
Kurzweil made his fortune designing the first machine that converted printed text into speech for the blind, and later developed computer scanning software. He was diagnosed with type 2 diabetes at the age of 35 but beat the disease by concocting his own special diet.
Known for his pioneering work in artificial intelligence, Minsky is a scientific advisor to Alcor as well as being signed up for the big freeze himself. In recent years, the professor has been endeavouring to give machines the power of commonsense reasoning at the Massachusetts Institute of Technology.
