Ouch :o Ahh guys you're missing the most important thing about lead... It's a cumulative poison. This means that when you take it in, it stays there and builds up over time. Now, what you breathed in while soldering today may not leave you with any ill-effect whatsoever, and you might think that you're fine... But after doing that so many times, you will reach a dangerous level of lead in your body, and can have some really serious effects like coma, brain damage, reduced IQ, infertility, cancer, etc. If you're feeling ANY effect of breathing in solder, like tingly lips etc, chances are that you also just breathed in a stack of lead. Seriously, if you're soldering in an unventilated room without a fan sucking the fumes through a carbon filter I reckon you're completely nuts. No offense intended, I'm probably talking to 90% of the forum :) Don't be cheap, go buy a soldering fan ;)
