Yesterday, I discovered that my elbow was causing me excruciating pain. I was mystified; I wasn’t doing any unusual physical activity the day before, and I don’t remember bumping into anything with my elbow. I have no idea what happened.
Except, now that I have a flaming hot lance of incredible fiery pain in my elbow, I’ve discovered that I bang into things all the time. Walk into the bedroom, there’s a door…of course I hit it with my elbow. Go to the bathroom…whoops, there’s a divider by the sink, give it a good whack. Is it possible for me to make coffee in the morning without bumping into anything? No, it is not. Now I go around hissing in agony and cussing up a storm.
At least I have learned the evolutionary function of elbows. They are knobby bony things that act as antennae to detect obstacles in the environment for clumsy people. No other purpose. Also, they have a direct neural connection to the expletive lobule of the brain.
