Yep thats how it works elader. They are gona preserve my brain and upload it into a new body. I want to go to heaven, but not after just 50 or so years here. I'd like to stay down here another 500 or so years. Born too early to witness the marvels of tomorrow in a utopian society. Not be immortal, just live A LOT longer.
Also, I'm not in US, but worldwide they can't do anything till 'clinically dead' however brain should still be intact and therefore theoratically can be unfrozen.
On to evading death, unnatural etc etc, I view this somewhat similar to defibrillation and conventional resuscitation. Therefore *THEORETICALLY* I should experience a near death encounter. Only this one will last hundreds of years, and not just a few seconds. And that is what I'm worried about.
As for costs, it isn't that bad, not too sure about Alcor, but another US based one, Cryonics Institute, charges 28 grand and a membership fee of $1250. Yes it is quite a lot of money, but comparable to other medical procedures. And I'd rather spend 30 grand to live longer than to get a new car or something. Life is worth more than 30 grand. If I'm too poor to afford that AND some cash in federal bonds/bank/bluechip investments (all 3 in case one crashes) to prevent waking up poor, then I'd rather die 'normally'.
On to the last issue of if this is insane or not, well back in the day people just died. Modern medical practice was unthinkable and they certainly didn't have CPR and a defibrillator. Think of this as a defibrillator, just that instead of doing it right away, they will only resuscitate me 200-500 years later, where I plan to live another 200-500 years and die peacefully.
Do I think this will work? No. I am willing to give it a shot though, after all I can't take anything with me to heaven

You enter this world by yourself, you leave by yourself. I find it real horrible that most people work all their lives for a house, some form of financial stability, qualifications. And then they die, just a few years after that. 40 years of effort. 10-40 years of rewards. If they lived to 180 instead of 80, they could get 140 years of stability. Sure, they have to work longer, but by now, things should have settled down, have a house, qualifications, financial security.
TL;DR What happens to people in a coma? Do they experience a near death encounter? I heard it can be distressing, not going to risk being confined to my 1m by 1m cell for 500 years, or worse, indefinitely.
