So while I am in the radiation machine I have found that counting slowly to 60 several times mixed with a few songs works great to pass the time.  When I would go to workout and i wanted the time to go fast but I didn't want to actually look and see how much time I had left, I would just start counting to 60 slowly and so it was actually a minute and a half would pass with each counting and then it helped the time pass. So now you all have a handy little tip to use when you want time to pass quickly.
