This could be really BIG----Scientists successfully reverse aging in mice

Seems they didn't try it on MJ.

"What if we discovered a way to not just stop it, but to reverse it? 

Scientists at Harvard think it’s possible. They developed a natural chemical that successfully turned old mice into young mice.

It seems crazy, but the Harvard team’s experiments revolve around what happens to cells as we get older. 

.....The team injected two-year-old mice with this younger version of NAD. After a week, they took tissue samples of those mice. Those samples appeared younger, more like that of six-month-old mice. To put that into perspective in human years, that’s like taking a 60-year-old grandfather and turning him into a 20-year-old college student. 

That’s impressive. 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."
