 Pat, where do we have in the United States 83-year-olds driving their motorcycle down to the vegetable market? We don't have it. We followed him to his home where he was up on a 30-foot ladder trimming a tree. He works in the fields about four to six hours a day. And he introduced us to his neighbor who was 90 years old without a wrinkle on his face. Neither of them use reading glasses.
