You may think it's funny, but it snot.

And now, since my caffeine-withdrawal-wracked brain cannot concentrate on anything serious today for more than a minute or two, a few words about boogers and snot.

A booger is an American slang term for partially solidified mucus from the nose; the British form is bogey. Boogers form when the mucus traps dust and other particles in the air. Mucus dries around the particle and, much like a pearl forming in an oyster, hardens into a booger. Wikipedia


Question: If you have acid in your stomach, why don't you melt?

Answer: Your stomach does have acid inside of it - hydrochloric acid - strong enough to eat through a piece of the metal zinc.

The reason your stomach isn't destroyed by the acid is our old friend snot, which is also called mucus.

Mucus is thick, sticky, slimy and gooey. And it's a good thing.

The inside of your stomach is covered with it. That layer of snot protects the stomach from its own acid. In fact, the miracle of mucus protects many parts of our bodies...

Mucins are a family of large, heavily glycosylated proteins. Although some mucins are membrane bound due to the presence of a hydrophobic membrane-spanning domain that favors retention in the plasma membrane, the concentration here is on those mucins that are secreted on mucosal surfaces and saliva.
