Vampires - Reduced Aging

“Do I have to become a vampire?” I asked.

“Eventually,” he said. “At first you will only have some vampire powers. I will make you a half-vampire. That means you will be able to move about during the day. You will not need much blood to keep you satisfied. You will have certain powers but not all. And you will only age at a fifth the regular rate, instead of the full vampire’s tenth.”

“What does that mean?” I asked, confused.

“Vampires do not live forever,” he explained, “but we do live far longer than humans. We age at about one-tenth the regular rate. Which means, for every ten years that pass, we age one. As a half-vampire, you will age one year for every five.”
