Our girls are hitting puberty six years early
Oh? What’s his supposed correct age for this?
I was taught in college that girls reach puberty earlier now than in prior centuries in part because they are exposed to light for more hours per day thanks to electrification, and puberty is in part triggered by an internal clock keeping track of how much light you’ve been exposed to in your lifetime.
Of course we leaned a lot of shit in college before the internet which turns out to be nonsense now. But I believe exposure to light is more important than we generally recognize. If you trace our evolution back to the beginning, you’ll find light sensitive cells far far earlier than anything involving actual vision.
