Shirt buttons still an issue.What I have found my left hand. seems to perform better than my right  I'm not \LHanded.What I would say  to anyone recently afflicted  by all means use gadgets but do try and get your hands to work around the problem. If I drop a coin or similar I have to pick it up using both middle fingers I always keep those nails longish.pulling plugs Out of sockets  forefinger and middle finger inverted V over its sides and yippee
