You don't have to sign a DNR or objection to autopsy to get cryonics. The autopsy objection is recommended, but not required. It looks like Alcor wants terminally ill people to sign a DNR, not typical healthy people.
I've signed a religious objection to autopsy (California doesn't seem to allow an atheistic objection to autopsy), but never has a DNR been mentioned to me by anyone at Alcor.
Thanks. That helps clarify things.
