Sugar, salt, and safety pins were also considered. Stairs, however, won out. They’re everywhere, they’re like free exercise machines, and they’re green. If you’ve been using elevators, consider taking the stairs… even if you just walk down them, it’s a start.
I’m currently a 3-flight guy. If I can get there in 3 flights of stairs or less, then I’ll skip the elevator. I hope to increase my range as I become more fit. In my previous life, I would take the elevator at the movie theater so I wouldn’t have to walk to the good seats.
