It was pretty extensive - we worked out 8 hours a day, 5 days a week, for 3 months, which I think is more than anybody in the Olympics. I thought well I don't need this, the girls need it, but it was a gift.
I can watch a movie and go, 'Oh, my god, that person is acting.' If you just listen to what the other person is saying, your response will always be genuine.
