Why surgeon are highly paid

A mechanic was removing the cylinder heads from the motor of a car when he spotted the famous heart surgeon in his shop, who was standing off to the side, waiting for the service manager to come to take a look at his car.

The mechanic shouted across the garage,

'Hello Doctor! Please come over here for a minute.'

The famous surgeon, a bit surprised, walked over to the mechanic.

The mechanic straightened up, wiped his hands on a rag and asked argumentatively,

'So doctor, look at this. I also open hearts, take valves out, grind 'em, put in new parts, and when I finish, this will work as a new one. So how come you get the big money, when you and me
is doing basically the same work? '

The doctor leaned over and whispered to the mechanic ........niamahfulat!!...try to do when the engine is running!!!
