August will mark the sixth year for veteran volunteer firefighter Jim Snedden to take part in the annual Leukaemia and Blood Cancer Firefighter Sky Tower Challenge, Stuff reports. Snedden, 80, is the oldest participant to take part in the charity climb, which involves scaling 51 flights of stairs carrying 25kg of gear. “A lot of people think I’m a bit mad, but that’s all right,” Snedden, who has served the Waiuku, south Auckland brigade for 56 years, said. The 2022 fundraiser has raised more than $430,000 so far.
