I rarely felt or noticed any real divide between girls and boys when I was growing up. Maybe it was because I was so involved in sports and competed with the boys. Maybe it was my mom and dad, who constantly instilled confidence in me and never made me feel as though there were boy activities and girl activities.

I don't really have many regrets. I did miss a lot of the events in the days leading up to my sister's wedding because I was at a U17 camp. There were moments like that growing up when I felt like I focused too much on soccer. But that's probably the reason I am where I am today.

I was the biggest tomboy growing up. Now I love playing with a full face of makeup.

I could be a model for one night. But I'm also a professional soccer player, and I like to be taken seriously on the field.

If you're healthier, you tend to have a lower demand for health services.

If you take 100 breast-cancer samples, 100 types of cancer have 100 different hallmarks of mutated genes. You could be nihilistic and say, 'Oh, God, we'll never be able to tackle this!' But there are deep, systematic, organizational principles at work in all that diversity.

My father was a research doctor at the National Institutes of Health in the early 1980s, and you couldn't work in the field and not know about D. Carleton Gajdusek, who my father often mentioned.

When I die, I will not be guilty of having left a generation of girls behind thinking that anyone can tend to their emotional health other than themselves.
