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!

@dantheclamman This is me! I took my kid in to get tested for lead, and he was fine. The threshold for lead is something like 0.5 parts per million. The Dr, who is my age, turned to me and said, "you and I would have been 20 ppm as kids."
Imagine how much smarter we all could have been.

@tito_swineflu yes, it makes me sad to think off all the potential lost, but happy to know society made the right choice
