The book contains stories of longtime couples with different stories of love. The featured couples share inspiring and terrifying experiences in each of their married life.

HOW DID THEY LAST?

On how they lasted 40 years of marriage, Thomas and Donahue stressed the importance of communication. It's their simple way to never break their relationship apart.

"Through the years you learn that everything is not that big a deal, and this isn't going to break us up no matter what, so you get used to saying, 'Ok, let's just talk it out,'" the actress said, adding that humor also goes a long way in marriage.

The two have become one of the famous pairs in the entertainment industry.

SCREAMING HELPS

Donahue, on the other hand, jokingly said that screaming helps them in the relationship. The funny thing about it, according to her, is that it helps one to listen.
