Climbed down the stairs from 25th floor

An evacuation drill took place at a building where my office is in the other day.

I climbed down the stairs from 25th floor. It would be easier than climbing up, but I heard that actually climbing down is tougher for muscle. In fact, I had muscle pain of my thighs. haha.

We were supposed to experience in an earthquake-simulation vehicle, but unfortunately, we couldn't due to breakdown of the car. What's a pity.

I experienced in a smoky room, which allow you to simulate walking in smoke of a fire. I couldn't see even 10cm ahead and was scared to walk forward. S, s, s, scary!!
