I grew up handling lead — electronic solder. Still have a fair amount of it around. I also had cadmium and mercury at various times.
I should not be alive, huh?
When a grade schoolchild ,I often made fake dimes by rubbing copper pennies in mercury in my hand taken from broken thermometers. As an adult I worked with mixing things in PCBs. Not that I now advise for such actions , but I survived service in WWII and see no lingering or deadly health effects and my doctors have not informed me of such.
