Going to the doctor's these days I had to laugh its like taking your car to the fixing shop. So many technical tools for today's intricate cars. Now lets face it. Cars have changed over the years. It used to be one man one wrench one fixed. But when it comes to people, have we really changed that much? When I had my short hospital stay I couldn't help but noticed how many welch allyn technical tools there were. I thought back to my car at the garage and had to laugh.
