Yes, so what? Whole body should out of question, anyway, because
neuros offer a better brain preservation quality. I'm not interested
in keeping my reflexes alive (why, I don't expect to ever use them) if
this correlates with brain damage.

1) Annealing doesn't work. You still crack.
2) You're worried about macroscopic cracks? Dude, you're a) real old
and/or sick b) frozen c) loaded with high-molarity cryoprotectant
toxic crap d) dead to start with. You really should not be worrying
about cracks.
Strong NT is not strictly necessary if you consider the uploader
route (freeze, slice, scan). But, yeah, sure, it would make things
much easier.

Why, below -130 but above -150, I would presume. Icing, that's that
thing on the cake. Don't get riled up on cracks, just because they're
nasty and visible. You should focus your worries on damage on nano and
microscale instead, which are far worse.

And how.
