Summary
Childhood lead exposure from leaded gasoline caused 151 million additional psychiatric illnesses in the U.S. between 1940 and 2015, according to new research.
Peak exposure occurred for Generation X (1966–1986 births) due to widespread use of leaded gasoline before its 1996 ban.
The study links lead exposure to higher rates of depression, anxiety, ADHD, and altered personality traits, including increased neuroticism and reduced conscientiousness.
Lead pollution also caused a collective loss of 824 million IQ points in Americans.
With millenials often there’s a split made between the early millenials and later millenials. People born before 1990 will have gone through a lot of early life and education without the internet. Where people born in 1990 and later will have had internet for most their childhood and education. This means the early millenials are a lot like gen-X and the later are much more distinct.
That part saddens me a bit. I’m part of the last generation of people that will ever know what the world was like before the net, without reading about it in a history book. It’s like being the person who was born before Tesla and Edison did their thing, and by the time they were an adult, the cities were lit up like giant inverted chandeliers with strange new loud self-powered vehicles starting to fill the streets.
