Yep. My first masters was in anxiety levels in relation to the different phases of the menstrual cycle, and premenstrual dysphoric disorder; using fMRI to study what was going on in the brain. Really interesting stuff, but because of the darn AS monster, I had to leave that program, but that's how I ended up in epidemiology. Which can lead to any number of health fields. I've always had a big interest in women's health stuff - it's so underrepresented in medical studies.
