"In 1914 – 1920, it was documented that children were going into convulsions and seizures because of lead paint. Some companies wanted to still advertise that their product was not the cause of their ailments but friendly and reliable. Dutch Boy was created to advertise to families that their white lead paint was safe. There were toys, paint books for children, advertisements saying that their lives are now better with Dutch Boy paint. From dark and gloomy to happy and cheery because of paint."
I've lost count how many people I've worked with that lead totally destroyed their lives and family. It can happen very fast, within months, causing confusion, aggressiveness, family and legal problems, banned from stores, early death, and nearly always loss of their job. The stories may seem funny until you know the cause and how it could have all been avoided.
Something like following the industrial hygiene rules at work and not eating candy bars with unwashed hands after making a new batch of heat resistant PVC plastic. It's not worth it welding in forklift battery trays without full positive pressure respirators. Don't dust the batteries and breathe the dust. Because 100% that lead will start replacing calcium as the neurotransmitter in your nervous system and it doesn't work as well. And it's the worst disability and death I've ever seen.
I believed after lead was taken out of gasoline, our country would be sane. That, I haven't seen yet, but it was a step in the right direction.
And don't play with liquid metal mercury.
