Hopefully one's temperament improves with age. I try to stay loose, but sometimes the best thing to do is get yourself away. One of the secrets is a good nap every day.
Fountain of youth
When I met my wife, who is very young, she'd say, "What will it be like growing old together?" I said, "I already am old!" Her father said he didn't know whether to call me father or son. Truth is, I like hanging around younger people. It gives you a sense of enthusiasm, of what's to come.
Keys to a good marriage
Love, patience, respect for each other, consideration — all that. But you have to have that connection, and that's something you can't force.
Leaving a mark
In America, we've got cowboys. As an actor, you don't reinvent something like the Western. You make it your own: "If I were in this situation, what would I do as a cattleman?" Suddenly your fingerprints are all over the place.
People come up and think it's the first time anyone's ever said, "Hey, I love the smell of napalm in the morning." You just have to smile and appreciate their support. Wherever I am in the world, I never get tired of someone reaching out like that.
The real deal
I do my own horsemanship in the movies. I do my own dancing, too. I did a tango movie once and somebody said, "Oh, yeah, somebody's doubling for him." No way.
