While I associate hibernation with bears, it doesn't carry a negative connotation (in fact, it's somewhat positive and cute) and can be related to medical hibernation. Cryosleep, as Daniel mentions, while better than a death-associated term, does require follow-on explanation of what cryosleep is. First use of ambulance to the future I could find was a LA Times interview of Steve Bridges (former Alcor President) published March 2, 1994, where he was quoted using the phrase "ambulance ot the future". I recall it from very early in my association with "Medical Hibernation" (;-), but it may be older. Steve may know. Interesting podcast discussion.
