FD...you appeared to be having a nervous breakdown, thinking about my letters to regulatory agencies, and now you endorse a wealthy version of Mathew moving cryonics into a medical clinic? That's quite a contradiction!!!
Other than maybe starting an IV once in a while, no one is going to be able to "brush up" on the skills of cannulation and perfusion, at a non-emergency clinic. Most people aren't going to go to a clinic where appointments are sometimes cancelled, so the staff can "freeze a dead person," so I doubt the staff would get much practice of ANY kind, and the clinic would be very unlikely to support itself. I don't think this idea would ever even get off the ground, much less fly.
