The London games mark the 24th anniversary of my winning two golds and setting the world record in the heptathlon. Someone is going to want it records are made to be broken - it's only a matter of time. I hope mine will outlive me.

Like most people my age my job is the main focus of my life. I don't have some kind of jet-setting fabulous lifestyle where I'm constantly in situations to acquire amazing anecdotes that's it.

Setting a good example for your children takes all the fun out of middle age.
