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.
If memory serves, you've said that your plan is to wait until your parents die and then kill yourself. Even if you do that and donate your organs, you should cryopreserve your head for a chance at waking up in a world you'd want to live in or could better help you with that. It's much worse a strategy than just trying to live to see it, but still better than final death.
Are you sure you can undergo neuropreservation while donating your organs (in light of simpleton's comment)? Has it been done?
