How a short walk can save 9.2 million people from Alzheimer's

Walking 30 minutes a day, five days a week might not seem like much. In fact, to someone like me, who is adament about getting to the gym, this would be considered a lazy week. But in someone who is at risk for dementia, it can make a big difference by helping boost your memory and delay the onset of Alzheimer's and other dementia issues.

And although these results don't sound impressive, Australian researchers say anything that delays the onset of Alzheimer's can make a big impact. How big? According to officials representing a study done at the Mebourne University,"'If illness onset could be delayed by 12 months, 9.2million fewer cases of Alzheimer's disease would occur worldwide."

But whether you're worried about Alzheimer's or not, you should definitely be getting some sort of exercise for at least 30 minutes a day, and walking is a great start.
