Marriage is insane: Matt Damon

Matt Damon thinks marriage is "insane" but he feels very lucky to marry Luciana Borroso.

The "Martian" actor believes the concept of bonding your life to another person is a "crazy idea", reported Daily Telegraph.

"I think marriage is insane. It's a crazy idea. But I love being married to my wife," he said.

The 44-year-old actor - who has stepdaughter Alexia, 17, and daughters Isabella, nine, Gia, seven, and Stella, four, with Luciana - believes his secret to having such a happy marriage is to always feel "lucky" to be with his spouse of almost 10 years.

"I wouldn't tell anybody anything else about their relationship. I'm lucky I found my wife. If there's any secret it's that. It's to feel lucky.
