Quoted from Isochronic_Frost:Worth mentioning that soldering is one of the of the more dangerous as that is direct lead vapors and that stuff can add up way quicker than you think.
That's not lead vapor coming off your soldering, it's the flux. Not that you should breathe that either, but unless you're soldering >1500F, it's safe.
Don't hold the leaded solder and then lick your fingers, of course. Wear gloves or wash your hands before eating.
