 I will never forget the morning, it's about 20 years ago now, I was attending a conference on the south coast of England, and having travelled there on my own, you know how you get into a kind of mood when you're away for a few days and out of routine, you say, I'm going to eat less, I'm going to train more, and all this kind of thing. So I decided I was going to get up early in the morning and go and swim in the ocean.
