I don’t know since when but as far back as I remember, I have been skipping every other step when climbing up a staircase. When I was young, skipping wasn’t possible. For one, my height didn’t permit such large footsteps, and for another, any attempt would result in a rupture in my shorts/pants. After I acquired required height, though, skipping steps became natural for me and has been so ever since, so much so that I have to remember explicitly not to do so when I am acting in professional capacity at my work. I would think that one would find a man in suit & tie jumping up stairs a little odd. When no one is around though, I am back to me!
It’s not really because I am always in hurry. I am a Type A personality but I am not always, in fact am mostly not, busy in doing anything so important that climbing stairs fastest would be become first priority. Despite that, as largely but not completely consistent with definition of Type A, I am generally “impatient, excessively time-conscious...highly competitive...incapable of relaxation...drive [myself] with deadlines, and [am] unhappy about the smallest of delays.” I walk faster than average as well. As the Wiki goes on to mention that this research is obsolete by today’s standards, so don’t you worry about my “insufficient level of self-esteem” and and “free floating hostility”. Nevertheless why I jump up staircase is interesting. Most teenagers do so but I guess most grow out of this later.
Perhaps there isn’t any great reason at all and I am simply too lazy to lift my steps twice the number of times and thus save on efforts required by skipping steps on staircases. In any case, I have to try to stop doing so soon to suit my adulthood more!
