A mechanic was removing a cylinder head from the motor of a Harley, when he spotted a famous heart surgeon in his shop. The heart surgeon was 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 famous 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 also can open it up, take valves out, fix'em, put in new parts and when I finish, this will work just like a new one. So how come I get a pittance and you get the really big money, 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 while it's running!"
Each profession has its own difficulties. So we should not simply underestimate and criticise others profession.
