So I’ve been taking the stairs at work. I work in a 3 story building, on the third floor. I remember when I would walk up a few stairs and had to stop and catch my breath. After my mile walk, going up the stairs is still a challenge for me. But I’m so close to not having to catch my breath at all. 1 flight left. I’m looking forward to the day when I don’t need to catch my breath to go up the stairs.
