Oh yes, there's definitely hints. I never would have imagined anthropology to be one of my areas of study when I was a kid though, and in fact I probably would have winced because I found people very boring (hell, I still probably find the -concept- of people, of sentience, more interesting than I find at least 9 out of 10 people). I always wanted either an artsy career or an animal-related career as a minor. XD
