Ian meets Tilly Lockey, a teenager testing the prosthetics of the future. Tilly, 15, lost both her hands as a baby after beating Meningitis. Frustrated by the prosthetics available to children, Tilly and her mum Sarah went on a journey to challenge this. At age 9, she became the first child in the UK to be fitted with a hero arm - a bionic prosthesis with life changing possibilities. Today she’s busy co-designing the prosthetics of the future, helping manufacturers to meet the changing needs of young people today.
