So the one shop was full of old bald guys who had lived much longer due to the health benefits of the fumes? ;-)
Seriously, while we may not always understand the full extent of our stupidity a bit of common sense usually saves your ass.
I mean we evolved that way - to survive without having all the facts.
Is it good to breathe solder fumes if they make your throat sore? Probably not.
Same goes for breathing the smoke from burning tobacco plants or drinking ethyl alcohol, do you really need the government to tell you that's a bad idea?

Years ago a friend mentioned he used to visit two assembly shops where they hand soldered; one used extractors, one didn’t. At the shop where they didn’t vent the fumes they were all bald… Hmm…
