In fact, Betty believes the dancing is what keeps Elmer healthy after nearly four decades with a disease that has slowly destroyed his kidneys.“That’s what keeps him going,” she said. “I truly believe it was the square dancing and the physical exercise. That’s why his kidney function went as long as it did.”Elmer was 35 years old when routine blood work revealed he had Berger’s disease.Berger’s disease develops when an antibody lodges in the kidneys, hampering their ability to filter waste, water and electrolytes from the blood. Over time, it can lead to blood and protein in one’s urine, high blood pressure, and swollen hands and feet, according to the Mayo Clinic.
