David Murdock does not count on living forever, but he does plan to live to at least age 125. To make it happen, the 89-year-old billionaire follows a strict regimen of exercise and a diet of vegetables and fish, and he's invested much of his cash into longevity research. Murdock made his fortune in the 1980s after taking over the nearly bankrupt Hawaiian owner of Dole Food Co. (DOLE, Fortune 500) He has since spent millions of dollars in recent years on scientific research on food science and nutrition, including how eating certain plants keep your alive longer. He started the California Health and Longevity Institute, which is a spa retreat that gives nutritional education, fitness training, lifestyle consultations, advanced diagnostic technology, personalized care, and medical screenings to enhance longevity. Another project, Duke University's MURDOCK Study aims to understand the genetics of diseases and cures.
