A bit off the main topic, but I've always wondered when we'll develop some sort of anesthesia/hibernation hybrid where when a person catches a disease that makes life uncomfortable or miserable, they would be put in suspension, similar to hibernation or general anesthesia, and reamin in that state until he or she is cured. For example, going through chemotherapy and radiotherapy, while unconscious, or even just dreaming, makes it way more appealing to me. I can think many, many other instances where this would be desirable.
