I think the sport of wrestling, which I became involved with at the age of 14... I competed until I was 34, kind of old for a contact sport. I coached the sport until I was 47. I think the discipline of wrestling has given me the discipline I have to write.
I find that everything I do is demanding, like Jack Bristow is a complicated man and I do a lot of explaining in the show, it takes a lot of energy and concentration.
