You learn something new every day, whether or not you realize it right away. There are no exceptions to this rule.
Today I learned the difference between bowler hats, pork pie hats and fedoras. Before today, they were all just fedoras to me. It never occurred to me that all three of these different hat styles had different names.
I also learned that Roseanne is Jewish, and that gummy shot glasses exist.
It doesn't have to be anything life-changing or significant or anything, just something that you learned. So AG, I ask you now, what did you learn today?
What I learned in boating school is that pepper spray hurts even when you close your eyes. Don't ask why I was pepper sprayed for, it was just a lapse of stupidity on my part at that time. *cough*
I learned that pagans practiced a ritual to increase the fertility and growth of their crops by dancing around with pitchforks, poles and broomsticks during the full moon. They were riding them, pretending they were horses. They leaped as high as they could to show the crops how high they wanted them to grow.
The Church claimed that they were trying to destroy the crops and flew up in the air with their brooms. By doing so, they were calling the devil. xD
Now we know where those witches flying with their broom's idea came from.
I learned that if you compare the performance of different rocket propulsion systems to cars, an ion thruster is like a Prius. Very efficient, slow to get going.
