If you are stockpiling food because you think things might get worse, what about mobility? You might need to walk to save your life. This video is from a September 1999 filming of Gary Null working out with guests who came to improve their health at Gary's Florida ranch. It was 95 degrees and sunny. The woman walking with Gary was 69 and she lost 10 pounds her first week on a gradual walking plan and eating real food.She was upbeat too. She was committed to saving herself.
