Alzheimer's and Activity

Just read this post in the New York Times about a study in Neurolgy  done on over 700 elderly people without dementia.  The subjects were followed for 4 years.  In that period 71 people developed Alzheimer's.  The researchers found that those who were in the lowest 10% for physical activity had twice the chance of developing Alzheimer's.  For some additional reading on this subject you should check out David Snowdon's book "Aging with Grace".  This video on the  "Nun Study"  is very good as well.  The moral of the story is to continue to be active both mentally and physically or as Nike once said "Just Do It."
