Manfred Kaiser has become interested in biometeorology while on duty with the German Weather Service in 1970. During boring nightshifts he began studying research material of the Medicine Meteorological Institute. Much later, in 2000 and 2001, he seriously researched the available material for his book: How the weather affects your health. The book has now reached its publication end and the content is now available for you on this website. Apart from bioweather and biometeorology subjects you can find interesting information on aviation-related subjects. Manfred Kaiser is an experienced helicopter pilot and air traffic controller. Radio-controlled model flying is his pastime and you can browse through the pictures of models he has built.
