Do you know what tonsil stones are? Technically, they're called tonsilloliths, and are made up of bacteria, dead cells, mucus, and other junk that can collect in the grooves of the tonsils. This buildup can happen due to stress, but the most common reason is tonsillitis (inflammation of the tonsils). The tonsils are supposed to trap bacteria and foreign stuff, but when they are inflamed, they are puffier. This puffiness can cause grooves in the tonsils to close up, which means any bacteria or foreign stuff would get trapped, until it's big enough to poke out of the groove. That's when you see them and get grossed out!
How clean is the air you breathe? If you live in a city, I'm sure you notice the difference as soon as you venture into the suburbs; air becomes easier to breathe and might even have a sweet scent! The American Lung Association's list of U.S. cities with the cleanest air made me realize I don't recognize most of these cities. Does fewer humans mean less pollution? Today Canada celebrates Clean Air Day, but you can join in no matter where you live. How can you (or do you) support cleaner air where you live? Some ideas are to bike more, carpool to work, or live closer to work. While we're on the topic of breathing, what's with this Asthmatic Playpen?! I'm not a child, but I want to sit in there.
