Hold on a second. You can get up between meetings, go for a jog, use a home gym, lay down and read, sit in your yard in the sun with your eyes closed, pet your dog, call your significant other or sit with them, shop for new shoes, study for a new job, take a video call from a recruiter, do your laundry, clean your bathroom, the list goes on.

Discipline is a personal problem not an office policy issue.
