Man Who Vowed to Live Forever Has Died



Many people have dreamed of living forever but for science fiction writer and physics teacher Robert C.W Ettinger it was a life’s mission. Ettinger who died this past weekend was a founder of the cryogenics movement and was frozen along with both of his ex-wives with hopes of one day being brought back to life.  Do you think that people who are currently frozen will ever live again?
Ettinger, widely considered the founder of the cryogenics movement, is being stored in a vat of liquid nitrogen in a facility just outside Detroit, along with 100 other "immortalists" who were frozen at death. Ettinger wrote The Prospect of Immortality in 1962, arguing that people would become nobler and more responsible if they were going to live forever — and if the world got too crowded, everyone could take turns going into suspended animation. He told the New Yorker last year that his frozen clients are "not truly dead in any fundamental sense."

If they froze him, then he's not really dead. But it is likely that he will never be revived, as one form or another of economic issues is likely to leave them without refrigeration at some point.

I wonder if they just dumped him into liquid nitrogen, or if they replaced some or all of his blood with the glycerin/DMSO mixture that is needed to stop ice crystals from forming and shattering the cells? My bet is they didn't. Of course, even better than that would have been for them to use their liquid nitrogen to produce liquid propane, which doesn't allow ice crystals to form all on its own, and doesn't boil when exposed to warm things (the boiling can disrupt the cells). This is a method that we use in my lab for cryofixation for electron microscopy. It ensures that there is no damage to bacteria or cells that we are imaging.

Why would any future person/company/government want to bring back people from this era?

99.999% of the population are dumber then rocks and could offer little to no factual data about the hows or whys of this time period.

I don't get it. There must be 100's of people who've been frozen for this. Instead of wondering about it, thaw one of the suckers out. Preferably one from the 80's. That would be significant enough, I reckon.

It's relatively easy to freeze someone, however thawing them's a different matter. Ice crystals form as they're warmed and rupture the sell membrane leaving them even more dead than before.

I heard recently that another founder or inventor of cryonics passed on - a second time. The freezer him and his wife were in failed and they became puddles.

"If they froze him, then he's not really dead." That would only (possibly) be true if they froze him alive, but they didn't. They froze him after he died. A dead frozen guy is still a dead guy.

"if they replaced some or all of his blood with the glycerin/DMSO mixture that is needed to stop ice crystals from forming and shattering the cells" It doesn't work. Replacing the blood with these fluids stops the blood exanding on freezing and damaging tissue, it does nothing to replace the water in other parts of the body. The end result being that the freezing and thawing process causes (currently) irreprable damage. I read a paper which suggested that the biggest challenge is probably repairing the damage caused by the freezing and thawing process.

He is a frozen entree. Current "freezing" does so much cellular damage it destroys the body on a cellular level. This has been known for many years. God bless him either way.
