The Stairs

I work on the 18th, and top, floor of my building. Well my empoyers are only on that floor so it is hardly the whole building. The main foyer is on level 4 and this week I have started walking the stairs with an aim to walk them at least once a day. So far so good - I acheived that goal succesfully last week with a slightly better time each day, I am sucking serious air at the top of the 14 flights though.
