As a result of a rare birth defect that affects the hip bone, Joby Mathew’s legs are under-developed, a condition caused by Proximal Fimoral Focal Deficiency (PFFD). But apparently he copes well without them, because at his 33 years old, Joby is a world champion arm wrestler. Moreover, in the near future he plans to climb Everest. I really respect such people. Hope he will make it!
