This was news to me. And of course, Brad took it upon himself to educate me...about sphincters
And so... for a moment tonight on the couch...Brad was like Bubba from Forrest Gump...talkin' shrimp.
Except Brad was...uh...talkin' sphincters: "well you've got about forty different sphincters...let's see....you've got your upper esophageal sphincter, your lower esophageal sphincter, epiglottis...which is a sphincter, pyloric sphincter, urethral sphincter, your sphincter pupillae…now that sphincter is basically the iris of your eye..."
Thanks Brad. You've made my night... I had no idea that there was a sphincter in my eye.
