Wu fan's thoughts on the escalator of the cold meal set

I often take the escalator when I go to the subway and shop. This is already a strange iron guy. I think about it in detail. There are a lot of things to think about.
I don't remember when I first saw this monster in elementary school. I thought it was a free big toy from God. At that time, we only knew that we had to rush down the escalator and see who could arrive at the bottom floor as soon as possible. We had a lot of fun in the laughter of our childhood playmates and the reprimand of our shop aunts. At that time, the escalator gave people more freshness than convenience. Today's children may not have that curious pleasure-because it is too much. As we grow up, escalators are everywhere and become the lazy thing of urban people. But why is it born?
The escalator helped me a lot when I was walking into the railway station with a big bag, and I was so tired that I couldn't help myself. It was a great invention without it, how can I win the great escape. Ah, people are really smart.
But when you look at the subway, people are squeezing towards the narrow and slow escalator, as if you don't want any money (don't think it's wrong, the cost of a subway ticket must be calculated), Wu fan always had to shake his head and turn to the cement step. In order to give myself a good reason, Wu fan always comforted himself when he climbed the ladder: an authoritative scientist said that every step of human life increases by one second. Haha, I took two steps in one step. Isn't it just two seconds? When I got to the high ground, I had a long life for one minute (one minute, not too much, at least let me get up in the morning and stay in bed for 60 seconds, after the dream of making a fortune), let's look back at the friends who are slowly suffering on the escalator and think of the prophet who invented this thing. You may have been killed by yourself for too many minutes. Hi, man, it's so stupid.
One day, at the entrance of Huaihai Road and Chongqing road, we were about to climb the escalator (this is an electric toy that really cares for the people). Suddenly, someone fell down on the ladder. Ah, it's a beautiful girl, wu lost his way to see the danger of the hero can not save the United States, five steps to change, pick up the beauty quickly jump onto the ground.
"Mmm ~~~~ Thank you, Uncle ." "You're welcome. How old is it ?" "Mmm ~~~~ Seven years old !" "Oh, you have to be careful. Why are you playing here ?" "Hmm ~~ This ladder is fun. It goes up, I go down, and I never go down ." "Ah, that's it !" Wu fan was suddenly inspired and inspired. Today, there are many ways to exercise and lose weight in the room. Isn't escalators the best way to lose weight? As long as I perform a trotting on the automatically rolling down escalator, I can assure that I will surely reduce all the undiminished items in a month five times a day. In addition, do athletes train long-distance runners to run on an accelerated escalator? Unfortunately, no boss will favor Wu fan's idea of saving the beauty of a hero-Let it go!
The escalator still carries thousands of lazy people every day. Wu fan, if there are not many people, he still did not discuss the ladder. Are you right or wrong about inventing it?

Wu fan self-evaluation: the development of science and technology and economy in the past two decades has made many rare things so common that they have forgotten how they used to survive. In the past, although old, there was an indelible memory.
 
Music Introduction: if you carefully find that there are so many beautiful things in Zhou huajian's life that the escalator is really a good thing and you don't want to go, isn't it a pity to leave it alone? * ^-^ *
