Almost everybody now and again has concerns about the future. It seems a very human trait to ignore what is familiar and always there, like waitresses in my last posting, and to be concerned about what might happen some time in the future.
People spend fortunes using complex tools to try to foresee the cycles of the stock market for example. When it was discovered that the ups and downs of parts of the European grain markets corresponded almost exactly to the sunspot cycle of just over eleven years, there was an immediate response, and lots of money available to study cycles in nature. Very well off people in the know can take advantage of cycles that are unknown to the ordinary person. The multi-millionaire W Clement Stone, used cycle research to his great advantage, and financed such research.
