This might sound sort of gross, but from time to time I’ll use the same coffee mug at home for a couple days. All I do is simply dump the old coffee out, quickly rinse and add fresh coffee. It’s a routine that works for me. Over the weekend I took a closer look inside my mug and noticed something familiar. There were rings from the old coffee lines, similar to what you would see with a tree if you were to cut one in half. With trees the rings show how much rain a tree had from year to year in a comparative scale. What could those coffee rings tell me about my mornings?
While the rings that I’ve identified are probably for five or six days, it’s hard to tell which one’s are from earlier in the week compared to my drinking habits later on. Aside from guessing which line belongs to which day, there’s a cluster of three or four lines that suggest that I’m drinking a consistent amount of coffee. I guess some information is better than no information.
