John (101) and Ann Betar (97) of Fairfield, Connecticut, tied the knot on Nov. 25, 1932. They've been happily married for over 80 years now. Together they have five children, 14 grandchildren and 16 great-grandchildren. They have been named the longest married couple in the U.S.

John and Ann Betar told ABC News that they considered themselves "blessed."
"We are very fortunate. It can be repeated and repeated," Ann, 97, said "It is unconditional love and understanding. We have had that. We consider it a blessing."
They said their secret to so many happy years together is simple: compromise and don't hold a grudge.
