Harrison Ford says he has a simple secret to a long-lasting marriage.
"Don't talk.
Nod your head," the 77-year-old actor joked in an interview.
Ford and Calista Flockhart are nearing their 10-year wedding anniversary, but they've been together for 18 years.
Flockhart is best known for her role in the late 90's TV show Ally McBeal.
According to CNN, Ford and Flockhart first met at the 2002 Golden Globes and wed eight years later.
