I'm an active duty Army soldier and suffered nerve damage to my left arm. By playing destiny actively I was able to ward off extra atrophy in my left hand due to using my thumb while playing. I just had surgery done to connect the medial nerve to the ulnar nerve in my forearm and not able to play well right now but hoping with practice I can re-learn how to play again. Thanks again Bungie for a game that ended up helping me physically!
