It's good to be difficult to know. Too many people are too easy to know.

I don't even have my own computer.

I've still got a small fitness and conditioning business where I travel round the world doing stuff for individuals and corporations, mainly fitness training.

If you work hard in real life, people tend to get in your way - either from inertia or prejudice - and they stop you achieving things. It's the worst thing about real life compared with sports, where you generally get what you deserve: if you're the fastest guy, you win; there are no other games being played.

The only limitations are mental. The guy who thinks positively will win.

I am an education ambassador, mainly working with schools.

Sport and health are so important to our nation that they deserve to be right at the front of people's minds.
