I couldn't agree more (about the cigarettes). I just thought I'd
mention them because a workplace hazard specialist once told me that they
found high lead levels in a group of welders they tested, and significantly
higher levels in the ones who also smoked.
[ Welding is the translation of metal into liquid and gas, not the same
thing as soldering at all. The comparison is flawed. I've been in the
electronics building industry as a hobby and profession since 1969 and
I've never heard of a study finding elevated lead content in solders.
Which doesn't mean you should put it in your mouth or not wash your hands
before eating and such. I wash my hands about 4-5 times a day when
building electronics. Besides the solder the electrolyte in caps is very
bad for you. ]
We used to work with tubes in our ancient electronics class ;-). A
lot of the prototyping fixtures were massive corroded old clips, that
couldn't be soldered to without using acid core flux. Today it's mainly used
in plumbing.
[ They're called "Faenstock Clips". ]
