Breathing Easy

Okay, I have a question: how important is the air we breathe?

I know, I know – it’s a ridiculous question. Look, I’m no dummy, and I know it’s pretty important that we breathe. But how big of a deal is it if, for instance, my apartment has mold? Is it going to give me serious long-term problems, or am I fine just leaving with the weird smell for a semester and then moving into a new place next year?
