I have long believed that due to a multitude of reasons, notable among them increased hormones in water and food, girls are developing physically far faster than they did even 10 years ago.
Evidently bra manufacturers have noticed a marked increase in a year range as short as 10 years in the past breast size increased from an average of 34b to 36c. That is pretty substantial in only ten years. Some of this is compounded by obesity admittedly. However there is a lot of science behind the environmental estrogen arguments (and in my mind why males are becoming increasingly effeminate).
While I cheer the increasing breast size of women, I have anecdotal evidence of a dark price they must pay: aging faster. If a girl is sexual developed years younger, has breasts sizes larger than her mothers, and is only in 8th grade by the time she is 25 there is a very real risk she will be past her biologic ability to have kids. It is one of those cases of the brighter candle burning faster. I knew one girl who when I was in 8th grade myself was very…developed…, she looked like a stacked 23 year old, hottest girl in school compared to other girls without anything. Fast forward to all of us in our 20s, and she looked like a middle aged fat cow. Tragic.
So girls: if you are hot, use it now, you’ll lose it extra fast.
Guys: Get busy the time is ripe.
