Well stranger things have happened IRL. In some remote village in India (or is it Sri Lanka, I forget) there is a 7-year-old, who assisted in his first operation aged 3 and performed his first (under supervision) aged 5. He has since been allowed to operate unsupervised. The operations were quite simple (I believe it was something like separating the toes of a girl with webbed feet), but nevertheless... He is, I believe, currently researching at the University of New Delhi.
