What I’d love to know is how chemical and thermodynamic means of preservation interact, for example if you can get someone to −40C in the permafrost, will chemical preservation suffice? What about −70C? How much difference does temperature make? (Arrhenius equation suggests that a 10C decrease roughly halves reaction rates, so −70C is 2^10 or 1000 times slower than 30C, and −140C is 2^17 or 131,000 times slower)
Agreed re: this.

Interesting that 2^20 hours is 120 years, so
an hour at room temp ==
a decade at −135 ==
a century at −170C ==
a millenium at LN2
