Cryogenic freezing with amniotic fluid

I must admit it is a very interesting thought. From the papers you referenced, I can see that the preservation of the organs in it could function well on temperatures above zero. My doubts appear when you put it in a context of freezing the human body many degres below zero (in order to minimize the metabolism activity). Here, by using the amniotic fluid, we could have the same problem as with the blood. It is constituted by 98-99% of water and therefore, forms ice crystals when freezing thus damaging the cells. The solution could be the cryoprotective fluid with nutritive value, based on the amniotic fluid composition or something like that.

Cryonics vs suspended animation

I definitely agree with you. The freezing institutions are considered "cemeteries" and thus, it means the fatal damage to an organism has already been done. It would be great if you could freeze a man alive, but that would be a murder or euthanasia, right? Concerning the ethical problem you stated, yes, this could be a tricky one. Even if we consider -196 degrees Celsius to be enough to almost completely stop the metabolic activity of the cells, we don´t know what happens with our soul. The mind would probably be deactivated too because it´s based on physiological neuron signals, but soul...

I like the perspective that brain is a kind of receiver system for consciousness, like a radio to the radio waves. Consciousness in this perspective is like radio waves - existing independently from radio, but manifesting themselves through it.
