Gray Matters

“Older people who walk 72 blocks a week, or roughly 6 to 9 miles, don’t lose as much brain function or gray-matter tissue as seniors who walk less, a study found.  Previous research has shown that brains shrink with age, which may cause memory loss.  It’s long been hypothesized that exercise may help prevent mental deterioration with age; this study suggests that gray matter may be the key to that protection.  Study participants (average age: 78) needed to walk the full 72 blocks to get the benefit, but walking more didn’t provide an additional help.”  Source: Neurology, published online Oct. 13, 2010  For information on anti-aging products click here.
