I mean, he was a really good teacher and we learned Physics at a high level...
But...Every time we took a test in his class, he gave everyone two Ginger Snap Cookies...
And a very small cup of warm Ginger Ale...
He insisted that the ginger would help us focus on the test and enhance our reasoning skills...
Of course, we all thought it was goofy, but we went along with our teacher...
And you know, the Ginger Snaps were not that bad and the Ginger Ale was sort of peppy...
And our class managed to pass that year of Physics and many of us went on to college...
And now...years later, I came across this article about Ginger being a "Brain Food"...
