I work on the puzzles for two reasons - one is for the enjoyment, and two is for rehabilitation. I am training my left hand to be of some use. Please don't judge the difficulty of your puzzles based on my times. I leave most of my times, in the hopes I can go back and improve my time down the road as the use of my hand improves. I have started to add puzzles from our collection of photos to help pay back what you have done for me.
