Walking may protect elderly men from dementia.
Elderly men who are sedentary or walk less than a quarter of a mile per day are nearly twice as likely to develop dementia and Alzheimer's disease compared to men who walk more than two miles per day.
Anyway, the headline made me think of this joke (in the extended entry because of indelicate language):
A man takes his wife in to see the doctor, and they're discussing the test results afterwards.Posted by Ted at September 22, 2004 06:07 AM"Well," says the doctor, "I've narrowed it down. Your wife either has AIDS or Alzheimers."
The guy looks puzzled and asks, "So what do I do now?"
The doctor says, "Go for a long drive this weekend, and drop her off about 10 miles outside of town. If she makes it back home, don't fuck her."
