Fitness and the Brain: Can a Walk a Day Keep Alzheimer’s Away?
In the U.S. some five million people have Alzheimer’s disease and 10 million boomers will be at risk for memory problems over their lifetime.

As clinicians, we have learned to recognize that jokes about “old-timer’s disease” and “Teflon brain” are often calls for help from seniors worried about their memory lapses. Living longer is obviously no fun if you cannot remember your home address or drive a car. Although we have made tremendous progress in understanding brain changes that accompany aging and dementia, no medications have proven effective for preventing Alzheimer’s to date. In recent years, however, more evidence is pointing to a non-medical way to bolster brain health as we age: exercise. [More]

Do I look fat in these genes? Exercise can cancel out effects of ‘heavy-weight’ DNA
More evidence today that our genes aren’t always our destiny — with an inconvenient caveat for couch potatoes: Physically active people who carry gene mutations linked to obesity are no more likely to be overweight than those without the variants — as long as they exercise at least three hours a day.
