A man resolved that in the new year he would learn why he was unable to please his wife.  He went to his doctor who gave him a thorough physical.

"Well" he said, "you're healthy enough but, look, your wife isn't intereetsed in sex because you're 50 pounds overweight.  I recommend that you begin a crash diet and exercise program.  I want you to begin by walking a mile evry day and call me in a week an a half."

Ten days later the man called his doctor.  "I'm feelin' good, Doc.  I've walked a mile a day for a week and half and I think I'm losing some of the weight.  But I also feel so much better."

"That's great" said the Doc.  "Is your wife showing any more interest in sex?"

"How should I know" he said "I'm ten miles away from her."
