there are two separate factors here - diet and race
more calories is causing earlier puberty
but also subhuman races have faster development due to smaller brains
Discussion
actually there may even be a third factor - all the xenoestrogens in the environment that are turning men into faggots and trannies might be accelerating development in girls ?
i see the enormous asses on women today and think to myself - it can't just be the calories. it has to be the estrogen in the environment.
i also wonder if the instagram chicks have gained access to hormones used by all the trannies to feminize themselves just like us menz used to do steroids to make ourselves more masculine ...
i wouldnt weigh a lot on that graph being accurate, its quite established girls generally bleed from 10 to 13 on in most cultures
i took that graph straight from Wikipedia.
