Answer:

Sometimes, one simple thing can change the answer to any question. Like here, for example. We are all humans. Whether you are Italian, Mexican or English. So, we all should have the same number of fingers, right? Well, not exactly. If you are an English speaking person, the number of your fingers will lower by one (and it should not, we are all the same after all). When speaking English we own four fingers and a thumb on one hand. In other languages, each person should have five fingers, among which is one thumb.
