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

The decathlon takes so long to learn that people who are good athletes don't want to go back to the beginning again.

But if kids take up things like hockey and football they will go back to it.

I am an education ambassador, mainly working with schools.

Having the ambition of becoming Olympic champion is a whole different ambition from wanting to be the greatest.

I think one of the things about being a good coach is to recognise when you have given all that you can. In fact there should be some sort of unspoken law that says that a coach cannot have anyone for three or four years - if you have not passed on most of the stuff you know in that time, then you are not doing a good job.

For kids it's natural to be competitive.
