The only moment I can pinpoint as the genesis of my interest in biomedical sciences was the winter of sixth grade, when I picked up a book about creativity and the brain . I found it fascinating, but what really struck me was that there was a book of several hundred pages that was mostly about how little we knew about the topic. It made me think. This was supposed to be a book about how much we've learned, and what it says is that the progress we've made is just discovering how little we know. This didn't faze me; it intrigued me. Because, of all the things we should know, surely our mind and body are of primary importance, yet we still have so much to learn. I have since learned that this phenomenon is not limited to the biological realm: gravity is one of the most important things in our lives, but we don't know the cause. But biomedical questions continue to fascinate me, perhaps because the answers are so vital. Sure, the cosmology is intriguing, but what about a cure for cancer, or even the common cold? How about a way to repair or bypass...
