Nine years ago, 47-year-old Jane Knight led a busy life. The British mum looked after an autistic son and worked as a therapist. She loved to write, paint, play piano, and sew. Today she lives as a triple amputee after operations removed both legs and one arm. It wasn’t a tragic accident that claimed her limbs — but a common disease that 25.8 million Americans and more than 3 million Brits have: diabetes.
