Walking about six miles a week appears to protect against brain shrinkage in old age, which in turn helps stem the onset of memory problems and cognitive decline, new research reveals.
"We have always been in search of the drug or the magic pill to help treat brain disorders," noted Kirk I. Erickson, an assistant professor of psychology at the University of Pittsburgh and the study's lead author. "But really what we are after may be, at least partially, even simpler than that. Just by walking regularly, and so maintaining a little bit of moderate physical activity, you can reduce your likelihood of developing Alzheimer's disease and [can] spare brain tissue."
I was walking a mile or two on average each day this year, up until March when I developed a disk herniation. I had back surgery on Oct. 4, and I am still taking it easy while my back heals. I will be glad when I can get back on the walking trail.
