Yesterday was a usual busy weekday in our unit. I work in adult Intensive Care Unit (ICU) as a nurse. I was going through my day, almost-without-intention or effort pacing in the halls from one end to another. I was logging 8 to 10,000 steps a day in my Fitbit. Well, that is not all I do, of course. I help other nurses and patients grabbing things, getting supplies, pulling meds for others, until my first my patient arrives from surgery.
