Fountain of Life Found? Old Mice Revived by Human Teenager's Blood

The fountain that we thought to be more like a spring that can automatically change an old person into a young one may probably be coming from us, specifically in our own stream of life -- our blood. In a recent study conducted by Alkahest, a California-based biopharmaceutical company, they found that a component of the human blood, the plasma, has significantly played a role in rejuvenating old mice.
