I've taken up the bad habit of chewing on pens when I sit at my desk, especially if I'm reading papers. I know that sooner or later, I'll accidentally gnaw through a pen and get ink all over myself, but in the meantime, it's having an unintended positive side effect. Aside from looking like I'm intently focused, I find myself breathing through my mouth instead of my nose. Usually, this is bad. It makes my lips chapped, my tongue dry, and my throat sore. However, since I have a coffee mug full of water at my desk at all times, I've found that I drink a lot more water during the day. This not only curbs my hunger, but keeps me more alert, and prevents early evening headaches caused by dehydration. So, I think I'll just stick to chewing on my pens thank you very much. I'm sure Dr. Brown, DDS would be furious with me.
