This is enough to get me motivated to work out more! "Researchers announced that they had coaxed the human brain into growing new nerve cells, a process that for decades had been thought impossible, simply by putting subjects on a three-month aerobic-workout regimen.

And there are clues that physical activity can stave off the beginnings of Alzheimer's disease, ADHD and other cognitive disorders. No matter your age, it seems, a strong, active body is crucial for building a strong, active mind." Stronger, Faster, Smarter: Exercise does more than build muscles and help prevent heart disease. New science shows that it also boosts brainpower—and may offer hope in the battle against Alzheimer's. http://www.msnbc.msn.com/id/17662246/site/newsweek
