Re: A Real Shot at Eternal Life?
How can you be so certain of the impossibility of science's ability to repair cryogenically "damaged" cells at some point in the future? The science is going at this from both ends, preservation (because of course not damaging something to begin with is better) and resuscitation. From an article in this month's The Scientist journal: Indeed, thanks to chemical cryoprotectants and sophisticated freezers, scientists and companies already have techniques to freeze sperm, eggs, embryos, and pools of cells such as blood or stem cells. And in the last decade, successful preservation of some solid tissues has offered hope that the long-neglected field is not dead in the water. In 2005, heart surgeons in Israel used an antifreeze protein from fish to preserve rat hearts at −1.3 ?C for 21 hours, then successfully transplanted them into recipient rats, where the hearts pumped away for 24 hours prior to dissection for analysis. In 2003, a California company similarly preserved a rabbit kidney at below-freezing temperatures and then thawed and transplanted it into a recipient rabbit, which remained healthy with that kidney alone for more than a month. And since 2000, researchers at the US Department of Agriculture have been cryopreserving the embryos of tropical flies for years at a time, then thawing them with ease and watching them hatch and live normal lives.

Re: A Real Shot at Eternal Life?
For $5, drop by my house, and I'll put you in the freezer......you won't be lonesome because I already have quite a few people stowed in there. Probably someone will keep the electricity on after I die, so you don't thaw out. I'll even put a sign on the door telling them to do that.
