Mechanic vs. Surgeon

A beautiful STORY...

A mechanic was removing the engine parts from a motorcycle when he saw a famous heart surgeon in his shop..
He went to him & said.. "Look at this engine... I opened its heart, took the valves out, repaired and put them back"...
So why do I get such a small salary? and u get huge sums....!
The doctor smiled at the mechanic and came close to his ear and said....
"Try the same when the engine is running."👌👏.
Classic!
