Lead is toxic at any dose.

This means is damages your neurons in any amount.

Contrast to say, copper, which doesn't start causing damage until levels exceed a certain tolerable threshold.

While lead is toxic at any amount, low amounts of lead cause low amounts of damage. It doesn't change the fact that the ideal exposure is 0 and over 99% of people have about 5 to 10 times the bond lead levels found in remains of our ancestors, and that even relatively low lead exposure levels from breathing lead in the air from just air pollution are linked to dramatically reduced IQ.

>99% of people have about 5 to 10 times the bond lead levels found in remains of our ancestors

99% of people live better lives than all of our ancestors, in every dimension.

if you're telling me it's because of lead, then lead is a good thing.

Silly.

[fsckboy]

it's silly hubris on your part to claim that you know that tetraethyl lead in gasoline was not a net positive for civilization: cheap gas in high compression cars leading to productivity gains? Could things have been better? you, of all people, have no idea.
