Harvard scientists have developed a natural chemical can turn the old into the young. Our cells lose oxygen as we get older, and without this, energy levels for everything inside of us decreases, and eventually stops working. NAD, a naturally-occurring chemical in our body, drops to about half of what our body creates when we're younger. So, the scientists decided to create NAD by using young mice cells and injected 2-year-old mice with it. They took tissue samples of those mice after a week, and the samples appeared younger, more like that of six-month-old mice. In human years, that would be similar to taking a 60-year-old grandfather and turning him into a 20-year-old young adult. Continue reading for a video and more information.
Dvice says that "what's even more impressive is that there aren't many adverse side effects to using NAD to reverse the aging process because it already naturally occurs in the body: all we're doing here is giving it a boost. Of course, reversing aging isn't the same as giving people immortality, but the potential to increase a person's lifespan with a better quality of life at an older age is there. Combine this with other aging breakthroughs, such as stem cell research, and we may all live 100 or 200 years longer."
