I take the stairs two at a time. Not occasionally, or when someone else does, or when I am in a hurry. I always take the stairs two at a time, (Except when carrying very heavy objects or team carrying)
The stair, like the wheel, is one of the remaining artifacts used in the ancient days as a remarkable tool. Today people find them a nusance. Humans, who are obsessed about speed and comfort in living, have developed more modern day tools to combat this ancient friend and foe. The Elevator is a wonderful invention for escalating objects, people, and ideas up several floors in little time in comparison to walking, especially in extremely high buildings. However if that extremely high building only has one elevator, it is usually faster to simply walk up, or down the stairs. Why? because you sit there, sedentary, at the floor you are waiting on, for up to a minute. In that time you could be almost there! When the building has only one or two floors, it is usually 100% faster to simply walk up the stairs.
Obviously there are times where the elevator is completely needed. For example, when the company I belong to had to move several racks of servers up to the second floor. Those things are around 500 pounds each...bringing them up the stairs would be the job of six men.
Another note I would like to attach to this thought is that "modern man", in its quest for simplicity and rapidity, have become lazy. And most are overweight from taking the elevator instead of the stairs. They are unhappy because they are overweight and they do not think themselves able "to take those blasted stairs." When, in most cases, if that person were to shun the elevator, they would find, at the very least, themselves aliviated of what ails them.
As always, my blog posts are opinion and not aimed at any person in particular. I love everyone and accept the way they are, with and without flaws and blessings. As I expect everyone to accept me.
