Not disputing this Bruce,

...And of us older than 26 (leaded gasoline was banned in '96) have been exposed to enough teratethyl lead to demonstrably affect our cognitive functions to some extent...

But surely location would have some bearing also? Those growing up in big cities as opposed to country towns? Even 3rd world places where pollution controls are markedly less, against me, (at least) growing up in rural Australia, with some very progressive controls in place and zero smog to live with.

Individual exposures vary; I was speaking more on the epidemiological usage of 'us'. but the vast majority of people were exposed to decades of lead to some degree or another, and the 'safe' dose is very very low.

Folks in the suburbs weren't living in the big cities, but they certainly were driving everywhere. And pollution controls like catalytic converters, etc were aimed at smog-producing emissions like nitrogen oxides; tetra-ethyl lead got mostly burned to lead oxides and went out the tailpipe as fine particulates. If you lived your whole life out in the boonies, you definitely got a lower dose, but if you lived around a gasoline powered vehicle. you got some.

Ethanol works better than TEL to raise octane.

Well, I'm sure their excuse was "Follow The Science", and turns out they publish excerpts and findings tuned to bolster certain targeted minds.
