I agree. I'm more concerned about taste. Should know at about 10yrs if it's time to quit.
I've got it in a "medical" freezer rated at -4f, but is holding at -8f, no defrost. Not cryogenic, but should help.
Being 60yrs old, I'll be lucky if I make it 20 more years![]()
It's nice to see America's youth planning ahead the same way old codgers like myself are.
