Alex,

>>>Death is defined as end (or absence) of life.>For instance, let's go with the definition you like: "death is the apparent end of our biological existence". What do you mean by "apparent" and by "biological existence"?
Especially by "apparent". To whom? To doctor or to shaman? To the latter hybernating body is "apparently dead" (and by the way, is very convenient object to illustrate resurrection to fool ignorant masses).
