Researchers in the US have recently run test on mice that can counter the affects of aging. When they took a young mouse's blood and injected it into an older mouse, the older mouse had a "dramatic reversal" in its muscles, brain function, memory, and stamina. Basically, the mouse becan to have the qualities of a younger mouse! Scientists are confident this will work the same way on humans
Scientist figure that in three to five years, this theory will be tested on humans. We might have found ways to increase lives! Also, with aging comes cancer, heart disease, diabetes and many other diseases. We may have also found a way to delay and reduce many death causing diseases!
