This book tells you how you can prevent the lessening of physical capacities we all fear that sets in around 40 and what you have to do to be physically and psychologically fit during your 50’s and 60’s. Physical exercise is the answer: Dr. Walter Noder has presented the successful program of the Bad Salzuflen Exercise School in form that enables everyone to practice heart circulation training (HCT)–in correct doses–for himself. And that means: remaining at an optimal level of fitness and alertness both on the job and in leisure time.
