Good point. As somewhat of a nitpick, I've heard that with some types of brain injury (especially those resulting from rotational forces and indirect impacts), a large portion of the total damage may be from secondary effects - my understanding is that this results from a chemical cascade that may only appreciably occur 4-30 hours after the event.
No citations and won't even bother for a hypothetical case - just a bit that I've read here and there. Google keywords are probably "secondary injury", "DAI", and "diffuse axonal injury".
I wrote a blog post arguing that people sign up for cryo more for peace of mind than for immortality. This suggests that cryo organizations should market towards the former desire than the latter (you can think of it as marketing to near mode rather than far mode, in Hansonian terms).

For those signed up already, does peace-of-mind resonate as a benefit of your membership?
If you are not a cryonics member, what would make you decide that it is a good idea?
