Repairing Hearts and Getting OlderA mechanic was removing a cylinder head from the motor of a Harley motorcycle when he spotted a well-known heart surgeon in his shop.The surgeon was there, waiting for the service manager to come and take a look at his bike.The mechanic shouted across the garage, "Hey, Doc, can I ask you a question?"The surgeon a bit surprised, walked over to the mechanic working on the motorcycle. The mechanic straightened up, wiped his hands on a rag and asked, "So Doc, look at this engine. I open its heart, take the valves out, fix 'em, put 'em back in, and when I finish, it works just like new. So how come I get such a small salary and you get the really big bucks, when you and I are doing basically the same work?"The surgeon paused, smiled and leaned over, and whispered to the mechanic..."Try doing it with the engine running."
