Just want to say:

Please don't breathe solder fumes.

That picture of everyone hunched over their PCB boards while soldering makes me cringe.

Use some form of protection via a fume extractor or face mask and when possible solder in a well-ventilated area.

I've met people who've completely destroyed their lungs and ended up with nasty lung cancer after years of day-to-day solder fume exposure.
