Both language and culture are learned by children without special organized programs of instruction, but motivation to learn is very high since language is the most effective means for a child to obtain what he or she wants. If the learning of a new language begins before lower adolescence, one is likely to be able to speak such a language with complete naturalness, but if learned after upper adolescence some hangover of a mother-tongue feature is very likely to persist. But not only do languages exhibit such learning patterns, but so do cultural traits, for example, shaking hands, kissing, and embracing.

By the middle of this century, some two thirds of the world's nation, with at least five billion people, will enjoy a standard of living which only the advanced economies now have. Some three billion of these people will live inn Asia. Collectively, the Asian countries will have a larger economy than the rest of the world put together.
The rest of the world will have to react to this millennial economic shift to Asia, and to the rising people of China. The rest of the world will be divided between the Euro-American countries, and the tow big peripheral powers, Japan and Russia. Russia is a huge geographical country, with ell educated people, and ill eventually recover. In terms of nations, it will be a world of much greater economic equality. Although there will still be poor countries, most will be quite rich. Inside these nations there ill be mass prosperity, but with a large minority in serious poverty, and a small number who are very rich.
