Comparing historical hair samples from people from when they were babies to today, a new study finds a nearly 100-fold decrease in lead from samples after the EPA's crackdown on leaded gas. Regulation works and it saves lives!

@ThePolishDispatch @dantheclamman People aren't talking about it, but the people in charge of businesses and governments around the world are exactly the age group who received the maximum doses of environmental lead. I strongly suspect that this fact is behind our worldwide political instability. I'm in this age range and I think that we need to take away grandpa's car keys.

@Patrickoldhiker @khleedril @ThePolishDispatch I worry a lot about collective impacts of cognitive decline and general mental health. It seems like there isn't much data to help us quantify whether our population-scale baseline has shifted, and that's scary to me.
