Surgeon to Surgeon

A mechanic was removing the cylinder heads from the engine 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.....

He said: "Try to do it, when the vehicle is running".

I recieve above article as a Joke...but I think this also got a deep thought embedded into it...Saving a Life is more Critical Job than Mechanical world around us...and Our Life is definately a most valuable thing.
