The statistics is pozzed. K selective races, East Asians and Europeans have it later while r selective races have it earlier (niggers and poojets). That's why the data says it "was older" back then, because it was only East Asians and Europeans they collected data from. Doesn't help that you got PFAS chemicals speeding it up.
Name a single animal on the planet that can have kids but "muhh probably have complications if it tried", this makes zero sense. If you start menstruation before the age of ~14, there is something wrong with you or you are a nigger.
