Well? There's got to be conditions.
A tipical 110 person is really old these days. God love them, but they are crusty little buggers and they don't do much, nor can they do much as many
of their senses have left them. So are we talking living as a human for 1000 years as an extention of one of these crusty little buggers at 110 and
then +890 more years? I'd gather if that were to be then they would be about a pile of dust that would start blowing away around 900.
Strangely so two would a vampire be, a pile of dust blowing away at its end.
What's the rate of decay? How if I were a vampire would I depart the plan after only 1000 years?
Come on, you can do better then this!
