To be clear, you want to bet that shaking your head side-to-side vigorously causes the same qualitative type of changes to protein concentrations along cell membranes as introducing a large concentration of toxic cryoprotectants?

...

No, I am not saying that shaking your head will rupture many of your phospholipid bilayers and in effect kill you.

Glad we could clear that up.

(What I am saying is "after the damage (e.g. cell membranes) has been repaired, certain information was not recoverable" not being a death knell for cryonics, since we accept a considerable margin of error concerning e.g. specific neurotransmitter vesicle locations in daily life without considering ourselves a different person just because we've effected a host of changes in distributions and arrangements. An example other than shaking your head, which also strongly affects cross-membrane distributions: SSRIs)
