Patricia McBride

My daughter arrived when I was five months pregnant with my son. We adopted Melanie from Korea; she was 2 years old, almost 3. I always wanted to have a family. I had a good example because Melissa Hayden was a ballerina in our company, and she had two children and danced afterward, and Allegra Kent also did.

I remember my dreams when I was a junior soloist. 'Oh, I hope I don't end here,' I thought. 'I want to do the ballerina in 'Scotch Symphony.' I don't want to be the little Scotch girl.' And I actually went beyond my wildest dreams. I worked with Balanchine. I had ballets choreographed for me.

When you dance, it takes a lot of stamina, but it never seemed like work 'cause I was doing something that I so loved doing. It was always a joy. And you know, to have beautiful ballets made specially for you is such an honor. I always said it was better than diamonds.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.

By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.
