Fountain of Youth?

Scientists have found a key to reversing the aging process in mice, and it has to do with the communication between the mitochondria and their nucleus. A molecule called NAD helps in the process, but the amount of it declines with age. There is, however, a molecule that increases the levels of NADs, and a week after this was injected into 22-month-old mice, their muscles exhibited the characteristics of those of 6-month-old mice: http://www.newscientist.com/article/dn24784-turning-back-time-ageing-reversed-in-mice.html#.UrSTt40tfgc
