I am 44 years old young. I was born with a disability called AMC or arthrogryposis multiplex congenita. The muscles in my arms and legs didn't develop properly before I was born so the connective tissues that would normally hold the muscle to the joint grew over my joints causing them to be fused or partially fused. I still have full sensors throughout my body and I am still able to walk short distances, but use a power wheelchair when I'm out in public
