Banning lead in gasoline was clearly a good thing for everyone's health. Breathing in lead in the air from gasoline combustion was bad and has been linked to heart disease, brain damage, cancer, etc.

My grandfather is 86, worked with lead cables for 30 years every single day, still sharp as a tack. Swing again.

Everyone has different tolerances and ability to deal with toxins. There was a guy that could eat metal. If you ate a pile of metal shaving you would probably die.

Lead is most poisonous when ingested. Casual contact is not generally harmful. I have 7 children and live in a house with lead paint, so I was curious.

Your point about RF shielding is 100% valid. I have not removed any paint from my home.

My point about lead was secondary but if you pay attention to current news, lead contamination of water is a big problem currently in the U.S. Perhaps there is another issue with the water, but lead makes sense, since when they replace the pipes people stop getting sick.

I would argue that mercury is a far bigger problem. Because it is literally put in your mouth. Chewing and consumption of hot substances causes vaporization of the mercury. It is pretty fucked.
