Failure once again of my doctor and therapists: coat wearing

 I don't yet have mittens that can be cinched at the wrist since otherwise with no use of the hand there is no way the mitten stays on. So today when walking in my nearby woods at 30 degrees with a north wind blowing my exposed left hand was getting cold.  That shouldn't be a problem, I just put it in my left jacket pocket. Not so, the left hand has no ability to even remotely get close to the pocket on its' own, so I have to try to get it in with my right hand, probably failed 6 times with my pinkie finger catching the zipper. After spending 15-20 minutes i finally got it inserted into the pocket.
