You wanna know what maturity looks like?
Look at this adult gorilla skull. Look at how rugged and defined it is, how large that mandible is, how tall that sagittal crest (the ridge on top) is. That's not for show: primate jaw muscles attach on top of the skull, and the gorilla's jaw muscles are so powerful they need an extra surface to anchor them. Look at how big the canines are too: this thing has a BITE. This is what an ADULT looks like. This is MATURITY.
Now look an adult human's skull. Look at that little faggot! Humans can barely bite through raw meat anymore, much less crack the shells of nuts. And where's the sagittal crest? There is none! The human's jaw muscles are so small and wimpy they just hang on to the smooth top of the skull with barely any anchor. But now look at one last skull: a juvenile gorilla's. See how much more it looks like the human than the adult gorilla? Why is that? Because anatomically, biologically, even adult humans are CHILDREN, teenagers at best. In biology, this is called neoteny: full development into a biologically mature organism is delayed or never reached. Up through puberty, humans develop much like gorillas, but whereas the gorilla emerges from puberty a STRONG and POWERFUL adult, humans never quite finish developing and remain physical adolescents all their lives.
The reason for this is DOMESTICATION, as a result of agriculture and its consequences. Humans, just like cows and pigs and dogs and house cats, are domesticated animals, bred specifically so that we never reach full maturity. Just as wolves were selectively bred by humans into dogs, which remain adolescent all their lives and never grow up into the wild, untameable killing machines they're meant to be, ancient humans were selectively bread by WHEAT into passive, childlike modern humans who will never see the true power their ancestors wielded. This process continues today, and has accelerated since the industrial revolution.
If you're wondering why you felt, at age 13, that you were as mature as the adults around you, it's because you were CORRECT. You reached the point, roughly, at which all modern humans stop developing and maturing.
In summary:
