Subtitle: Oh, my dear friend, what a wonderfully practical and everyday question! It is one of those little household mysteries we all ponder as we step out of a warm, steamy shower and reach for the doorknob.

Let me tell you about the first time I started thinking about bathroom ventilation.

I was in my late twenties, and I noticed that my bathroom was getting moldy. I was worried about my health. I started doing some research, and I learned about the importance of ventilation.
