He he he
I was a bit of a dumbass when in late high school and college. And was competing for a short time in car stereo contests in the 1985-1986 range. I had a car stereo in my station wagon that was 148DB.

It was loud enough that with certain music, it would cause a variety of symptoms. Nausea, vision blurring to the music because the fluid in your eyes was getting squished. TO the most horrible feature... foaming bowel movements. That was likely from the 10" subwoofers under each of the front seats.
Needless to say, that combined with around 600 hours in Cessnas with faulty window and door gaskets, I have some pretty healthy hearing issues. Not deaf, but I have completely different hearing in each ear. Certain voice frequencies I can hear in one ear and not the other.
Oh yeah and the rock concerts.. I never missed one.

Swarf and splinters..
My son had some headaches and nausea kicking in for some unknown resons. They ended wanting to do MRI and CAT scans.
They asked... Do either of you work on a metal lathe or mill?
erm
Me why?
THey walked me around the corner and showed me one of the machines.. a HUGEEEEE Ring around a table. They said.. THAT.. is a giant electro magnet.........
I was impressed.. but thought it wasnt a big deal. Till they told me they have lots of problems with people who have ferrous metal in thier fingers and hands. And they have a lot of problems because the magnet removes them forcably. And they just migrate right out of your skin.. and through whatever is in the way I gather.
Needless to say.. I stayed well away from that room.
