In Why I Walk, I devote a chapter to the health benefits of walking to the individual. There's also a plethora of good info on the internets about how putting one foot in front of the other on a regular basis helps everything from your heart to your joints and so much more. Here's a short piece on 8 items from Rodale News. From the post:
A lot of attention has been paid to getting in 10,000 steps of walking, jogging or running a day. A 40-minute, two-mile walk will chip away half of those steps, and everyday activities can usually accumulate the other half.
Here's one of the eight that caught my eye:
Italian researchers enlisted 749 people suffering from memory problems in a study and measured their walking and other moderate activities, such as yard work. At the four-year follow-up, they found that those who expended the most energy walking had a 27 percent lower risk of developing dementia than the people who expended the least. This could be the result of physical activity’s role in increasing blood flow to the brain.
