It's not as if we aren't already - why do you think NASA was set up?
If I was going to live forever, then the aging process would have to be stopped before I agreed to taking the wonder drug or whatever it was that made me live forever. I certainly wouldn't want to live to the age of 150 (Or more) and end up looking like a walking corpse!
Like Centurion said, if you can't make your own decisions, why should you be essentially forced to live, simply because others can't stomach the thought of letting you pass away, or because the law says so?
I totally agree with Euthanasia - as long as it is properly controlled, ie. 2 Doctors give the say-so, all the legal stuff is sorted out first, not forced into it, that sort of thing.
Isn't it more humane to let someone die happily, surrounded by their family whilst they can still make their own decisions, or whilst the pain of their disease hasn't yet become unbarable?
I just don't understand why the thought of letting/allowing a loved one die is less favourable than letting them live until their body falls apart around them, and they are unable to even look after themselves like even a child can.
In this day and age where we can give people the choice and support they need to make their own decisions, why does the law forbid this? If anything, the law should support and cater for choices to be made, so people aren't forced to suffer an unbearable life of misery and pain.
I know the law is simply a framework of rules, regulations, and punishments that are designed to regulate the way you live so that the people can be protected and assured of justice, but isn't the stopping of a humane way to die a form of preventing the justice that people need and want?
Euthanasia should be allowed, especially if we're gonna live forever.

Skeeter, i'm not an expert in Cryogenics or anything, but I believe the reason why only the head is usually preserved, is simply because it is easier to preserve just the head.
Crygenics invloves freezing the body/body part as quickly as possible. The longer it takes for the freezing to occur, the bigger the ice crystals are, and the more damage that is done to the body by the ice.
It is sort of the same with ice cream really. The longer the ice cream has taken to freeze, the larger the crystals are, and the 'grittier' it tastes. This is also why ice cream doesn't taste as nice when you get to the last couple of scoops at the bottom of the tub. The constant freezing and thawing of the ice cream means new ice crystals have formed at un uncontrollable rate, leading to large crystals, and a gritty texture.
The smaller the object you freeze, the easier it is to control the freezing. It is easier to freeze the head in a controlled manner, than to freeze the entire body.
Scientists also believe that by the time they have cracked how to Crygenically freeze a body and reanimate it, they will be able to 'build' a new body to attach the head to anyway, so the body essentially doesn't matter.
This is why only the head is frozen, and not just the body. As Undated said though, this might be the 'old' way of doing it, afterall, new techniques for things are always being tested. Perhaps they know how to controllably freeze the entire body now?
