Themselves Aztecs called themselves "Mechin" or "tenochka" and "atlaltelolka" - depending on the city of origin (Tenochtitlan, Tlatelolco). As to the origin of the word "Mexica» (mexica. From which, in fact, is the word "Mexico"), it expressed a very different version of its etymology: the word "Sun" in Nahuatl, the Aztec name of the leader Meshitli (Meksitli, Mekshitli) - type of algae grows in lake Texcoco. The most famous translator of Nahuatl Miguel Leon-Portilla, says that the word means "middle of the Moon." Self-name "tenochki" possibly comes from the name Tenocha - another legendary leader.

People have always wanted to be healthier, but when it comes to asking them, "what should you do in order to be healthier?", they get a bit puzzled. Actually, we know what to do, so the only question is, "do we want to do it?". In case you really want to be healthier, you must know some rules. First of all, you should not eat fast food, because it will lead to obesity. So, if you are very hungry, you will better eat an apple or something that is not that "dangerous" for your stomach. Secondly, do the sport! Nowadays, doing any sport may be expenssive, but no worries, you can do some exercises right at your home! If you don't know which ones to do, there are plenty of them if you look for them in the Internet. But I should also mention that we should not overwork ourselves, because, in that case, our body can easily get too tired. Hence we can try to be healthier gradually. Anyway, it's important to say that we should ask our doctor for help, because he knows better what is good for our health.
