Don't Tell Buffy

I love the news stories that pop up in the headlines on slow news days:
"Vampires A Mathematical Impossibility, Scientist Says"

This might be important news if the math were good, but it's not. This "expert" assumes that a vampire sires new vampires at the rate of one a month, which is not even close. And the effect of slaying and accidental sunlight exposure is not even factored in.
