My girlfriend/SO's grandfather died last night, running on a treadmill when his heart gave out.
He wasn't signed up for cryonics, of course. She tried to convince him, and I tried myself a little the one time I met her grandparents.
"This didn't have to happen. Fucking religion."
That's what my girlfriend said.
I asked her if I could share that with you, and she said yes.
Just so that we're clear that all the wonderful emotional benefits of self-delusion come with a price, and the price isn't just to you.
Also, don't bother with whole-body preservation. It's useless, because regrowing a body is the least of revival problems, and it's harmful, because your brain spends longer warm while the whole useless hunk of meat attached to it is cooling down. Plus it costs more.
I'd feel more comfortable with that if we knew more about the extent to which the glial cells around the heart -- not to mention the remainder of the nervous system -- play a role in learning, decisionmaking, emotion etc. I'd hate to lose any non-recoverable data from those systems and have to recreate it, e.g. learning to walk again or being missing emotional reactions, or who knows what else. I think I'd want to keep the "useless hunk of meat" around, just in case, even if it had to be separated from the head for better cooling.
