Human brain is stupid - fit to the wrong environment. I was thinking the other day: Babies are afraid of strangers, any new people, especially if those are a little scary. But that makes no sense in modern countries - nobody ever threatens this child, and if on off-change somebody does, he'll try to be as "friendly" as possible when doing so. Children scares make no sense! Adult anxiety makes no sense either!
