During the course of my shift at work, I walked up and down a flight of stairs a minimum of 26 times last night. That is like walking up a 26 story building. Each flight of stairs has 18 steps. That is 468 steps. And I do this a minimum of twice a week, sometimes more. And that doesn't include all the regular walking I do. Seriously, is it any wonder my whole body aches at the end of my shift? Who needs a Stairmaster? Who needs a gym? I have 8 hours in a prison, 5 days a week.
