You probably took your vitamins and played outside when you were a kid.
Vitamin D supplements/sun curtails high lead levels.
Lead concentrations in kids go up in the winter, it was studied and proven in the 70’s yet we need to spend Billions of dollars to strip lead based surfaces from everything.
As in global warming ~ it’s the sun stupid :)
(oh, and they lowered the lead threshold, like the cholesterol levels - take your pills)
