cryogenics! i saw this programme on 5 last nightabout being frozen after death?

Question

would you go in for this after u die and what would you like the world to be like when you wake up?

Answer 1

Oh looks like we have a lot of experts on here.
Which one of you can prove that it won’t work.
I love experts, like the guy who said it was impossible to do heart transplants.
Cryonics is already used for embryos and sperm
How can you know what will be possible in the future
I am signed up for cryonics myself and am also part of the standby team.
If we listened to experts we would still be living in caves.
The classification of death is changing, it has already, from stopped breathing, heart stopped, now it has to be brain stem death, who is to say at some point the brain cant be re started.
Ice damage is now becoming less of a problem as techniques improve.
Freezing damage is part of the problem, but you are missing the point. Cryonics isnt a cure, it is more an ambulance to the future. If future technology is able to revive a suspended person, cure what they died from they could also be in a position to repair freezing damage. Aging would also be reversible so you wouldn’t come back an old person. Even now people are working on the aging problem. The cells don’t actually explode, the latest protocols remove and replace a large amount of the water with a protectant and the formation of ice crystals is avoided, this is known as vitrification, which means glass like.
Once suspended you have all the time you want, the body is no longer decaying.
Given the choice of being eaten by maggots or sent up a chimney I will stick with my cryonics. If it doesn't work I have lost nothing and won’t know anything about it. If it does work it will be mind blowing.
I am not paying that kind of money outright, a simple life insurance policy covers the cost.
We can’t prove it will work and nobody yet has proved it wont.

Answer 2

when water freezes it expands as it crystallises. Crystals are sharp. All cells contain water - it is the medium of biochemical reactions as they occur in solution. Freezing would cause cellular water to expand and crystallise bursting the cell and its contents including DNA, but as the cell has been destroyed losing the DNA is of little consequence. Think frostbite. This is cell death due to freezing.
On the other hand some amphibians have genes that express an antifreeze that allows them to be deep frozen (but still alive) preventing lysis. If they developed a gene therapy that would allow us to produce this, then cryogenics may be possible.
But, as has been stated, why would anyone want to be frozen in old age (when most folk die - would you want to be killed in your prime of life in the hope this technology is true?) and then be defrosted into a world that has no family, friends or need of you?

Answer 3

Most people don't realise that there is more than one type of "ice", or solid phase of water. If you're able to cool water fast enough, it doesn't become ice and expand, but can form a different type of solid. If you were able to cool/heat some living organism fast enough (all the way through), you might be able to avoid damaging the cells. This could be a possible basis for cryonics.

Answer 4

I saw this too, and I certainly wouldn't pay $175,000 for the privalege. The world is already overpopulated, when your time comes, that's it, why possibly come back to a world that you don't know

Answer 5

yes i would go for it and hope the world would be a better place
when i wake up 30 years later

Answer 6

You won't come back! Freezing will irreversibly damage your cells (actually they would explode) and DNA.

Answer 7

No, I hate the cold.

Answer 8

waste of money dont you think
