Jack Reynolds became the oldest man to ride on a zip line ever last week. His impressive feat was recorded live on the morning talk show "Good Morning Britain" in the U.K. The zip line at Grizedale Forest in the Lake District is around 400 meters long and 60 meters high, and Reynolds went down it at 40 miles an hour.Reynolds described the experience as "perfect," while his daughter Jayne called her dad "indestructible." He was presented with a Guinness World Record plaque by an official from the organization, officially making him a record-breaker. It's safe to say viewers were loving Reynold's antics:This isn't the first birthday challenge that Reynolds has done. Last year, he rode a roller coaster on the show as he turned 105. The year before that he took to the skies in a Tiger Moth plane. We cannot wait to see what challenge he takes up for his next birthday!
