What do vampires and Jesus Christ have in common? They both believe that drinking blood holds the key to immortality, although Christ was speaking metaphorically. Blood mythology dates back thousands, if not millions of years. Adherents to Christianity believe you must symbolically drink the blood of Jesus Christ in order to gain eternal life. The belief in vampire mythology is that the blood of a supernatural creature will spare you from immediate, human death.
We are surrounded by stories that the secrets of anti-aging, longevity, and immortality are in the blood. Vampirism and Christianity aren't the only belief systems or religions that focus on blood as the path to immortality. Take a look at any ancient religion, and you will find the belief system is based on blood. Blood sacrifices are a common theme, and most ancients believed blood held sacred power. Blood mythology is giving way to science in the search for the fountain of youth. Controversial, yet exciting, is the theory that infusing healthy blood cells from the young can reverse and possibly cure age-related disease. It's called Parabiosis.
