If anyone is wondering... I'm Nicole. My internet handle pretty much everywhere is niccast, so if you see that on, say, rockclimbing.com, it's probably me (but 'nic cast' is not). I'm a pediatrician with a strong liberal arts education and an undergraduate degree in engineering. Any medically-related edits I make could be said to come from an authoritative source. All other edits are pretty much just a well-educated person's judicious, discriminating use of Google :)
