Lesson learned after 80 years of marriage

Charlotte and John Henderson are the oldest living couple in the entire world. At 105 and 106 respectively, these lovebirds have lived most of their lives at each other's side.

The couple first met in 1934 at the University of Texas. They tied the knot during the Great Depression and spent a whopping $7 on their honeymoon. (That's not a misprint. "Seven" dollars.) They are about to celebrate 80 years of marriage, and they are not keeping the key to their longevity a secret. It's simple really. According to John, "You just have to live life in moderation, and be cordial to your spouse."
