“For better for worse, for richer, for poorer, in sickness and in health, until death do us part.” These vows are repeated hundreds of times a year, in front of thousands of witnesses, to represent a binding contract between husband and wife. The beauty is when these words ring true — 63 years later.

Frank and Mary Jo Havlak are the focus in a New York Times Op-Doc series by filmmaker Joe Callander. The Havlaks have been married for almost 63 years, but for the last eight, Mary Jo has suffered from Alzheimer’s. Her memory of weddings, graduations and holidays is gone, but this has not deterred Frank from holding on to that commitment he made to her all those years ago.
