You get to exchange the current problems like cancer, aids, famine, war and lack of apace travel for the future problems like super aidsncer, future famines and wars and fighting off aliens?
Anyway, in order to freeze you you have to die (before hand or by the freezing itself), and hope people find a no umbrella way to revert death on good conserved corpses in the future.
It's a lot of gambles. I would bet on uploading your mind(but that probably will only produce a copy of you). Or brains in jars and steem cell you way to immortality.
Well, that's why I mentioned the as-yet fictional cryosleep option. Surely someone will have to invent that sooner or later if we're serious about spreading this human plague throughout the stars...
The stem cells option is intriguing, but as far as I am aware that just involves prolonging one's life, not taking a temporary hiatus from it. Besides, if I was rich enough to buy up on stem cells I could probably afford to chill in a sensory deprivation tank for as long as I pleased to escape from reality, surfacing occasionally for a gourmet meal prepared by my personal chef.
Hell, my usual misery might not be so bad to begin with if I had shitloads of money.
Also, my personal problems don't really include any of those things, at least as far as I'm aware. Who knows, maybe a nice, big war (possibly against aliens!) would be just the thing to give me a purpose in life!
Just unfreeze me when there are alien invaders to shoot.
P.S. as far as I can see you're doing a pretty damn impressive job of looking after your family, given the circumstances. They're lucky to have you.
