Good point. I make a big deal about it at my booth, and my entries in the schedule will read: REAL CRYONICS: BEYOND BREDO , FILM/PRESENTATION ON THE STATE OF THE ART IN HUMAN CRYOPRESERVATION. FDGD THEATER, FREE but it might be good to toss a brief bit about it into the souvenir program lest someone who doesn't make it to the booth or the presentation should read it. I do have a line to walk (how fine is debatable) -- asserting the infeasibility of the procedure without undermining the appeal of the event. People have no problem with my saying "Grandpa's mind is gone"; but we really don't know exactly what _is_ in there -- there's probably plenty of DNA (more than in those mammmoths that have been found in permafrost, I'll warrant), but exactly how much more than that is unclear. That's why I consider it a point on the cryonics continuum -- permafrost and dry ice are right near the bottom, many of the preservations of current patients are at miscellaneous points in the middle (depending how long it was before they were preserved, whether and how extensive an autopsy there was, whether the preservations was done with or without cryoprotectant perfusion and with what, etc.), and the latest vitrification techniques and cryoprotectants are at the top. Somewhere in there is the "memories/identity irretrievable" line; being certain which side of the line something is on doesn't mean the data point can automatically be thrown out. There's a sense in which cryonics is a matter of intent; there were lots of "flying machines" before the Wright Flyer that didn't fly. I won't belabor this further unless somebody insists on giving me a hard time about it. Let me see about adding a clarifying statement to the Q&A. Note that I don't get much space.
