To bend over backward about the merits of freeze drying, I'll say that with the proper research, which (as should be very clear) will hardly be simple, I can conceive of making some form of freeze drying work successfully for brain preservation. Yes, existing forms have many problems. But that doesn't really solve any issues, particularly for those who (for one reason or another) favor it. HOWEVER, I will note that nowhere has there been ANY move to work on freeze drying with the same kind of effort and precision that to date has gone into cryopreservation. That alone tells me that those in favor, to prove their seriousness, either have to start doing the required research or admit that their interest is simply not deep enough. NO one else is working on it, so the finger points to them. Here is an historical analogy. Some time ago, we learned to fly using balloons, and after years of work, we learned how to direct these balloons to where we wanted them to go. Yes, balloons did have lots of problems. However those who wanted some other means of flight studied hard and after a great deal of work, study, and experimentation created AIRPLANES. These had their problems too, but they were different problems. For reasons which may not be permanent, balloons and dirigibles have now fallen into disfavor. Some people in favor of airplanes probably went to those working on dirigibles and asked them to work on airplanes instead. This never seemed to work, and these people are now totally forgotten. Others got to work on making airplanes, despite all the trouble and difficulties. Perhaps those who claimed to want airplanes really feared flight in any form, and their interest was just a smokescreen to cover up their fear. Perhaps not --- we'll never know. To translate: I personally believe that long term preservation of patients which we cannot fix now is NOT going to be an emphemeral technology. It will be with us literally millenia into the future. I also do not expect the current cryopreservation technology, or vitrification, or any methods now known, to be used (say) 500 years in the future. Something better will be devised. HOWEVER, we live now in 1997 and must deal with what we know best in 1997. Future possibilities can be dreamt about when we lie in our hammocks resting on a summer day, but they save no one NOW and are just as evanescent as clouds. That is fundamentally why I support cryopreservation and want to be cryonically suspended. Best and long long life to all, Thomas Donaldson Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=8431
