A man was celebrating his 80th birthday and his 50th wedding anniversary.

A reported asked, "Sir, how do you account for looking so fit?"

"Well," the old-timer told him, "when we got married, my wife and I made an agreement that any time we saw an argument coming on, I would grab my hat and walk three times around the block. You'd be surprised what 50 years of outdoor exercise will do for your health!"
