Looks like you learn the same way I do Frank. Burned my eyes glancing at an arc welder (feels like sandpaper under your eyelids if you want to know), had to have a sliver of steel dug out of the center of my cornea, driving a bar in the ground not using safety glasses (no nerves in the cornea so it didn't hurt - but scary), got 2nd degree burns on my eyelids after looking into a burning barrel to see why the paint can had not exploded, as it did (that skin is REAL tender, and guess how many times you blink in a day), stuck a screwdriver in my eye when putting on brake springs without the right tool - just flipped the eyelid inside out and slight scratched my eye - scared the socks off me though. And that's just the short list. I won't tell you about the time my brother and i made an electric chair and had to test it. He tried it, not me. :o
I'm happy to say my brother is still around and I have all my fingers, toes and eyeballs, but just because of dumb luck.
I'm just finishing up putting the engine back in an old car (should have been done long ago, but it is a case of - while I have it apart I might as well change this or that - got to do the ball joints and I'm done).
Two of the new tools that I now find indispensable are the blue nitrile gloves you can get at Harbor Freight and a digital camera.
My hands no longer have black cuticles or stink of cleaning solvent and the camera lets me take pictures of what the brackets and connectors should look like when I start to put stuff back together.
Heal quickly :)

(by the way, I did clean the engine valve gear in lye. When I took the gloves off I did find a pinhole and a red spot on one finger. Felt kind of like a sliver, but took a few days to clear up.)
