Micah & Opa's Adventure

Today, Micah and I went to visit his ENT specialist for a regular checkup.
We had a bit of a wait, so Micah proceeded to demonstrate how this chair could be controlled up or down by means of the foot pedal. He explained to me that the pedal had arrows on it for up and down, the pedal is "stuck" [connected?] to the chair, and that's how it works.
