A couple from Ohio celebrated 68 years of marriage this past Sunday surrounded by family and friends, and their trick to a long marriage -- zipping your lip.

"Keeping your mouth shut,” says Howard Cully. “Being very careful of what you say. It's better off not to say anything than have to go around later with your head between your tail and it's like 'I'm sorry for [what I] said' because you've already said it."

The couple had their first date at a local pool, and not long after that they got married, nearly seven decades ago.
