Happy Days star Henry Winkler relishes his fly fishing hobby - because it helps him hone his skills as an actor.
Winkler, who played leather jacket-wearing The Fonz on the popular U.S. TV sitcom, admits he always makes time to enjoy the great outdoors because it strengthens his game and clears his head.
He says, "As an actor sometimes I would push. You cannot force (things) on the river because the fish will break your (fishing) line. You cannot force yourself in a scene, you have to find the rhythm with your fellow actors.
"For me, it (fly fishing) is like a washing machine for your brain. Any perceived problem or real problem is washed away by the river."
