My Dad Needs To Get Up and Do SOMETHING!!!

My dad just had rotator cuff surgery and has been layed up at home!! He is so bored! He has been doing more and more every day but his arm is really sore. He has to wear a sling for 10-12 weeks, and it is his right arm. He is trying his best to do things with his left hand....but sometimes he is clumsy. He woke my mom up at 3:30 in the morning because he spilled italian salad dressing all over the kitchen counter, cupboards and floor.
