Troubleshooting

I am a computer geek. I troubleshoot computers. If I can't figure out the problem, the computer doesn't run reliably. Big deal. I spent yesterday at a hospital with a friend. He has been having trouble with his eye sight for more than 3 years. Two operations later and the doctors are still puzzled. They don't have a clue what is causing the problem. I sat in the waiting room and watched many patients filter in and out. We are at an Institute, a state of the art facility. The best specialists in the area. I wondered how long each patient had been visiting the doctor. Sometimes I think I have stress. Yesterday made me put my stress into perspective. A doctor's stress level must be unmeasurable.
