It is thought that 200 years ago in Australia there were as many languages as there were tribes, which means about 500-600! Linguists have not found any other language in the world related to those of the Australian tribes. However, after years of study they (49) - to establish that the grammar of the old Australian languages was very complicated, comparable to those of ancient Greek or Latin. Aborigines, the natives of Australia, did not wear any clothes and also slept naked. This was extremely interesting for white ethnographers, who wanted to discover why the aborigines (50) - from cold and did not get ill. After various medical examinations it turned out that the aborigines (51)- an extraordinary blood circulation system. The blood which reached the heart was warm, but the blood flowing through the limbs could be cooled down to 12 degrees Centigrade without any bad consequences for the individual. The arms and legs of the natives (52) - ice-cold, but it was enough for the aborigines to do some exercises in the morning to speed up blood circulation and the (53) - organism worked as normal.

       I guess that in the nearest future we will be able to invent shirts or sweaters that will serve us as electric body-heaters.

       These shirts or other items of clothing will be made not only from silk, cotton, or woll but they will also contain tiny, long, electric wires penetrating a whole thing thoroughly.

       Apart from that, a small battery will be added to such a shirt powering the wires with energy needed to produce heat. The electric current flowing through the wires will start heating them and as a result the wires will start emitting heat towards a human body.

       I think that we can also weave the wires into shoe soles to achieve the similar effect to keep our feet warm on a rainy and chilly day. It can be much more difficult to do because of the fact that shoes are made of tough materials as skin and rubber but I guess that we could change the wires for electric plates.

      These inventions will definitely help us feel comfortable outside in autumn or winter and they can also help us to cut our expenses on heating of our houses !
