Agreed, though my post did say "normal body temperature", not room temperature.

I understand. I was going with Alicorn's description - and normal body temperature incidentally 'feels' a whole lot worse to me.

We're just talking about instinctive subjective reactions here but I note that one of the appealing things to me about your specific proposed explanation was that it didn't talk about temperature or bodies at all:

“If there were a medical procedure which, if all other attempts to treat a life-threatening condition failed, could preserve the patient indefinitely in a suspended state in anticipation that future technology may enable them to be resuscitated and treated, would you be open to undergoing this procedure as a last resort?”

That sounds good to me. And to Alicorn it translated into imagery of room temperature and sleeping. The same translation that feels 'inviting' to Alicorn feels revolting to me. Perhaps your (Ata's) instincts are also somewhat different to mine in as much as 'normal body temperature' feels better than 'room temperature'.
