Das kluge, lustige, gesunde, ungebremste, glückliche, sehr lange Leben

These are the big questions: How does one live a fulfilling life? What can we influence in this life - and how? What are the things that people who live to a very old age are proud of at the end? And what do they regret? How do relationships shape our lives, what influence do culture, nutrition, exercise, genetics, as well as education and wealth have? Klaus Brinkbäumer and Samiha Shafy traveled on their world journey to Sardinia, Okinawa (Japan), and Loma Linda (California) to find out why so many more people live significantly longer there than elsewhere. The journey continued to Russia, China, Thailand, Hawaii, African islands, and the American East Coast - and quite close by, to Austria, Switzerland, Denmark, and all across Germany. How does one achieve a successful life? Scientists and centenarians can answer all these big questions.
