THE BODY REVOLUTION
Over 10 years in the making, The Body Revolution is being developed with break-through results that unlock the secrets of aging. In late Fall 2010 scientists at Harvard Medical School made a stunning announcement claiming to have reversed the aging process in mice.
The study's leading author states:
We witnessed a dramatic reversal in the signs and symptoms of aging. ... This is the first time that a very severely aged, degenerative state, equivalent to what you might see in somebody who's in the eighth or ninth decade of life, has been reversed.
Scientists are now working on applying these exciting research results to humans.
Telomerase reactivation reverses tissue degeneration in aged telomerase-deficient mice. Nature: 469, 102–106 (1/06/2011)
at the National Primate Center have dramatically slowed down aging with an all
natural regimen in non-human primates.
Digital University is collating and coordinating the research results of medical institutions from around the world. Major developments regarding recent advances in humans will soon be announced.
This medical video dramatically exposes America's Number One Killer.
What is shown in this video can be prevented. It can also be REVERSED with a medically-proven paradigm that requires no drugs, pills, statins or surgery. The Body Revolution will show you how.
