This is one of those things that requires theremin-heavy music in the background.
That'll do. Read on.
I StumbleUpon-ed the Baader-Meinhof phenomenon article this afternoon. The Baader-Meinhof phenomenon, something I'm sure everyone's experienced at least once, is that bizarre synchronicity whereupon you learn something for the first time and then hear about it again a short time later. The term itself was coined by someone writing an editorial in the St. Paul Pioneer Press about experiencing the B-M P; their readership responded overwhelmingly with similar stories.
I was glad to know that this is apparently a Thing, but didn't think I was going to write about it... until tonight! David Malki of Wondermark notoriety had Twittered about using the Valsalva maneuver; I made note of the unfamiliar phrase, but antithetical to my nature, did not Wiki it. I know, I'm disappointed in myself too. But then, not an hour later, I was goofing around on the Straight Dope, and Cecil Adams explained the very same Valsalva maneuver in the article I was reading! And, the Valsalva maneuver just happens to be exhaling forcibly with your mouth and nose closed to clear your ear canals, which I do all the damn time because my inner ear bits get congested especially during allergy season!
Baader-Meinhof phenomenon! Spooky stuff!
