We father pointed out in an e-mail to me that I didn't explain all the household hazards that he was raised with.
Here in his own words:
"Finally, I omitted our playing with asbestos as children. It is a mineral that we'd get a hold of somewhere and play with it. The fibers were all loose. Let's see, I was also raised in a house filled with cigarette smokers. There were many times when a pall of smoke lay so think it was difficult to see across a room. Hasn't bothered me yet!"
What he didn't mention was that he is in his 80s. Imagine, lead toys, playing with mercury, general aviation pilot, second hand smoke, asbestos exposure and he's still here.
