Research undertaken by Germany's society of Nuerologists and the Stroke Society showed that 15 minutes of exercise a day made a surprising contribution to improving overall health. The study in Taiwan had over 400,000 participants whose health status was checked regularly over 8 years.

The results showed that over a lifetime there would be an expected increase of 3 years of life expectancy as well as a reduced chance of developing cancer and diseases of the cardiovascular system.

The general conclusion was that the more a person exercises, the less chance they have of falling ill.
