Joe is an accountant. He’s in a rush in the morning, so he skips breakfast. He sits at his desk all day, crunching numbers and mindlessly munching popcorn from the break room. There’s no real lunch to speak of—just some trail mix and an apple at his desk. He sits some more, and then drives to the climbing gym after work.
