Check out the TV show Mythical Beasts "Curse of the Vampire".
It sounds like a silly show, but it goes into the myths of beasts from human history and explores their origins.
The vampire episode explores the belief of consuming blood of the young to prolong life. Pretty interesting. Combine it with the recent research on the proof that young blood if beneficial to the aging. I would not put it past people like Kurzweil and his ilk (look him up) to prolong his life with young blood.

We (mankind) tried to kill them off, but we didn't get them all.
