All 3 of mine run exceptionally high fevers over nothing, I don't even freak out over a fever of 104 or 105 because it was so routine when they were all toddlers. As they've gotten older they seem to get fevers much less frequently, but they still run pretty hot. I don't think it has anything to do with their intelligence (unless you listen to my mother- she's sure it fries their little brain cells).
