Average Age of Menarche (Onset of Menstruation)
12.5 years. Interestingly, a study in 1962 showed that this age has decreased by four months every decade since 1830.
That means that girls in 1830 weren't having their periods until they were just shy of their 19th birthday!! Seeing as how they keep starting younger and younger it's no wonder they become sexually active a lot sooner, too!!
And if the trend continues at that rate, the obverse of that is that by 2244 (exactly 21 decades in the opposite direction) girls will start having their periods before they get into kindergarten!! In another 17 decades, they'll start having their periods before they're even born!! I guess that means they'll be born with tits, too!!
Does that also mean that menopause will start at about 35??
