Do you know why the young American population (and the rest of the copy-cat world) is wearing their caps with the peaks backwards?

Well, I did this question to myself and I found the answer. It is very easy:

As you know over every cap’s peak there always a emblem or sign, saying things like “The lame runners association” or “The cats council for mice care”.

The average human speed at a normal pace is of 2.5 miles per hour. If two people walk one over the other is like one of them ( the one wearing the cap) was stopped and the other walking over him at double that speed, that is, 5 miles per hour. If the normal visual range to see and read what is written in the cap starts at or about 20 feet from the object, that means that the person approaching the one wearing the cap would have only about 5 seconds to read what is in the cap.

But let’s analyze with an engineer’s mind this timing:

The approaching person needs at least a couple of seconds to be aware of the other. Another two seconds to realice of the cap and find the sign interesting. Do you think that in the remaining second is he going to be able to read what is written in the cap? The answer is NO. For so, the new American generation (and lagging copy-cats) as clever as they are, are showing those signs to the people walking behind them.

In this case (and unless the person behind pass him what usually does not happen in a society with no hurry) the relative velocity (the velocity of the person behind in relation to the person wearing the cap if he was stopped) is zero. That is, as far as he is behind he has time to easily read the legend on the cap (it could be a lifetime). For so they are wearing their caps backwards. Easy, isn’t it? It’s not only a matter of fashion.
