I love Mental Floss. They are constantly filling my well of useless information. This one surprised me, and answered something I had wondered about off and on for my entire life. I learned that the reason your nose gets stuffy one nostril at a time is because your nostrils switch off and on. You have a primary and a secondary, and through involuntary muscle regulation, they take turns.
I hope you enjoyed this bite-sized bit of science. Now get out there and have a good weekend!
