So Neanderthals really did "live fast and die young". I guess
since their creative, neotonous childhoods were so short, they
wouldn't have had a chance to develop the kind of mental
flexibility modern humans have. I've also seen speculation that
they couldn't develop much culture, because they didn't have
enough old people for oral tradition to start. If they grew up
quickly, they may have also aged quickly, which would support
that theory.
