(Newser) – Just three 45-minute runs a week were enough to reverse the aging process in mice, according to researchers at McMaster University in Canada. Scientists genetically modified the mice so their mitochondria would break down faster, causing the mice to age faster. Half of the mice were then put on an exercise program, running on mini-treadmills three times a week. "After a few months of exercise there were absolutely unprecedented changes," a researcher told AOL News.

"It went way above and beyond the muscles and heart, but also the brain, gonads, kidneys, and other organs. It was absolutely exciting." They also had shinier, thicker hair. "Every organ was better off in the mice that exercised," he continued. "And not just a little bit better, it was a 100% improvement." His recommendation? "It all about keeping yourself moving every day."
