I see him walking while working as a way to keep his physical self exercising alongside his mind, not because he can’t handle being alone with his thoughts. He even mentions that if there’s a stressful meeting, he can walk off some of the stress.

He also works remotely, and it’s important to take the opportunities to move around while remote. It’s easy to stay in the house all day, especially in a snowy winter, but getting some movement in is important for many people to have a happy and healthy life.
