Walter Bingham looks like a typical grandfather, but spent a recent birthday skydiving. JERUSALEM (JTA) — When Walter Bingham moved to Israel following a long career as a host on British radio, he applied for a job at Kol Israel, one of the country’s leading broadcasters. He came in for an interview but was rejected: At 80 years old, Bingham was told, he was past the station’s mandatory retirement age. Other journalists might have retired. Bingham did not. The experience, he said, made him “realize this is a very ageist country.” Undeterred, he kept finding opportunities to work. Seventeen years later, Bingham is still not retired. And this month, at age 97, he was certified by Guinness World Records as the world’s oldest working journalist.
