It's so hard to express yourself, because swimmers are pretty much paying attention to a black line for hours out of a day.
I want to be able to look back and say, 'I've done everything I can, and I was successful.' I don't want to look back and say I should have done this or that. I'd like to change things for the younger generation of swimmers coming along.
I concentrate on preparing to swim my race and let the other swimmers think about me, not me about them.
If I have one message to young swimmers about taking care of their bodies, it's definitely take care of your shoulders.
I cannot control what goes on in another lane and this is how I focus on the Games. There is no point in being nervous of other swimmers. It's just about focusing on yourself and what you need to do in order to perform at your best.
The newspapers loved pinup pictures of pretty young swimmers, and as a national champion, I got more than my share of space in the sports pages.
My favourite Friday treat is to drive out of the centre of Cambridge, where we live, and go for a swim at the health club I've just joined out in the countryside at Quy. It's a lovely pool, inside a converted barn. Usually it's just me and a couple of other swimmers there.
I think ninjas are probably quieter than SEALs, but we are better swimmers, and also better with guns and blowing things up.
Swimmers provide much healthier role models for teenagers than the catwalk.
There are younger, stronger swimmers coming up and they are hungry. I can't influence what they do, I only know what I can do and I know how greedy I am to defend my title.
