I think we're all very curious as children. Developmentally, we start off a lot more curious in life as babies. I've always thought that was amazing that it's one of the traits that just seems to disappear as people get older. We ask those questions that know self-respecting teenager or adult, whatever, ask because you don't want to be laughed at and so on. Those are much more diffuse characteristics than I would have attributed to curiosity. But I think actually you'd be surprised that something is basic and as inherently interesting as curiosity,. It's not a huge literature or at the very beginning.
