You always see people coming back to the sport, and I've always thought, 'Gosh, when you're done playing, wouldn't you just want to stay at home?

I donate lots to charity. I don't necessarily tell everybody the number or what I do.

I don't think I should be underestimated.

I come from a family of working women, my mum went to work two weeks after I was born - my parents had no money, there was no choice.

I always tried to hide the fact that I was an athlete. I just wanted to be normal.

I could never have gotten back into my career without the undying support of my husband, who works full time at a stressful job! We decided that we were going to do this as total partners and it is a 50/50 deal with us.
