"Freezing your brain is as scientific as stitching corpse-body-parts together to create a living human."

Mmmm, not sure this is a good analogy.

While cryonics isn't proven science yet, we have frozen dogs, pigs, and other animals and revived them after a few days. Granted, this isn't a human, but if I am ever in a situation where the end is there in front of me with a little bit of time to contemplate it, I'd rather take the frozen brain/body route.
