Freezing yourself.

Here's an idea, but its going to be a small view since i got to go.

How bout dehydration and then a sudden freezing, so brain doesnt die and the cells dont burst.

Lol, I suppose you would have to be pretty dry for that to work, right?
That would be so cool, though, if it could work...

The other unstated bonus of this dehydration technique is that you could be transported in a much smaller volume, given how much of the human body is composed of water. Like a small cardboard box.

The cells will shrink to fit the fluid volume prior to freezing. A slightly more feasible idea might be to replace the water with a suitable liquid. (one that is non-toxic, will displace the bodily water and which won't cause damaging expansion on freezing. Not that I can think of any such chemical...)

An issue that I've never seen raised for human freezing is protein deformation (if there is such an issue?). Given the limited acceptable temperature ranges for enzymes, might freezing someone for a long time lead to proteins degrading and breaking down due to the stresses caused by bending and shape changing at the lower temperature?

Well, that would make reviving you horrendously hard.

Assuming that you could dehydrate a person extremely quickly so that you don't die from having literally no blood pressure at all, rehydrating one would be so much harder. I think the trauma of rehydration would be actually greater than having some ice form

Just thinking of it, without water, your cell membranes themselves would break down.....no hydrophobic lipid interactions would allow membrane phospholipids to basically go crazy and boom, no more clearly organized cells left anymore...

But if you were frozen as the portions of your body dehydrated like say start at the toes and go up. then there would be no time for your cells to react they'd be frozen and place and if it gets cold enough and your kep bacteria free you will be able to stay perfectly fine. And when rehydration came to you'd be unfreezing as you re hydrate.

Even if it works(dehydratating and so on) I really do not think this is a good idea. Imagine you wake up after 100-200 years. All of the people you loved would be already dead. You will be alone and it is highly probable that you will live in a world completely different from your own. Look only about 100 years ago... Do you think an aristocrat (for example) from the end of XIX century could live in this world... Does it worth the risk? After all the death comes to us sooner or later. Trying to outsmart it never leads to anything good.

It's more complicated when it comes to a dying person who has not chances of survival... But this choice also has many disadvantages.
