I can't run forever. I decided to go back to school for my degree, because I know now there's more to life than track.

I can feel the wind go by when I run. It feels good. It feels fast.

I was single-minded and I had tunnel vision. Now it's time for a change.

I've noticed that since I've been pregnant I see babies everywhere. I love talking to them. I never used to really like kids that much. I guess it comes out of you naturally.

Before me, sprinters retired at 23 or 24. I run because I still like it, I can make a living, and I feel I was born to do it. And because people tell me I can't do it.

I am thrilled to be 31, still running and having my daughter watch me even if it is on TV.

Whatever muscles I have are the product of my own hard work and nothing else.
