Cryo-freeze

Cirno: "I'll cryo-freeze you together with some English beef!"

This requires bulky machinery and other equipment that one person is unlikely to be able to maneuver. Furthermore, even if current technology could cryo-freeze an entire body, the process would take many hours. Dr. Stein made inquiries and found out that a specialist in the field of cryogenics had made a breakthrough just a few weeks before the murder that allowed him to safely freeze single organs, but not entire bodies.

"Both the original injury and the cryo-freeze did him a lot of damage, some of it permanent. He was forced to take a medical discharge, which he — hm! — did not handle well. It's not my place to discuss those details.” “If he was injured badly enough to need cryo-freeze, he was dead!” she said, startled. “Technically, I suppose so. 'Alive' and 'dead' are not such neat categories as they used to be in the Time of Isolation.”

"What are you going to do with her?" he asked. "Nothing, Dr. Sanders. You are." Sanders shook his head. "What do you mean?" - "We've got two new clients, Dr. Sanders, that need to be put into cryo-freeze..."

Oh I hate this, and she did it on purpose, I'm floating in mid grav feeling like I'm in cryo freeze like the old days. “Lasko you were never in cryo freeze, that has not been used since the star stream was discovered.” Good point, and it is kinda good for the back. “Just be careful of the...” Ow, the transition. “Sorry Lasko, but I told you to stay seated.” The tone in her voice tells me she kinda enjoyed that."
