I have arthritis in my right elbow and both knees but it doesn't prevent me from playing golf. Having a total left knee replacement next month and my only concern is how long it will be before I can play 18 holes again!
Strangely enough my screen cracked over the weekend with no interference from me. The question is can I be bothered to replace it as it probably won't be cheap.
I have a similar issue with tv remote. The volume has to end with a 5 or a 0 even to the point of telling my wife to adjust it accordingly. She thinks I am an obsessive about a lot of other things too.
That's Spurs for you. We never know which team is going to turn up, how they will perform and if they will win or lose. At the moment we are relieved to get a point a game!
