How to grow old healthily while still having fun is explained by the renowned expert Prof. Dr. med. Kleine-Gunk in his latest anti-aging book for pleasure seekers. Being a pleasure seeker does not mean celebrating New Year's Eve every day. Rather, it is about enhancing one's ability to enjoy. The perfect tool for this is the principle of opposites. We often enjoy more intensely after experiencing the opposite. This is a well-known effect, familiar to those who fast, for example. Generally, life and aging occur between opposing poles such as rest and movement, stress and relaxation, or head and gut. The secret to a healthier life is not the middle ground, but the balanced back-and-forth between these poles. The author presents current scientific findings in an extremely entertaining way, with surprising insights.
