>> Vehicle when he spotted a well-known cardiologist in his shop.
>>
>>
>>
>> The cardiologist was there waiting for the service manager to come and
>>
>> take a look at his car when the mechanic shouted across the garage,
>>
>> "Hey Doc, want to take a look at this?"
>>
>>
>>
>> The cardiologist, a bit surprised, walked over to where the mechanic
>>
>> was working on the vehicle .
>>
>>
>>
>> The mechanic straightened up, wiped his hands on a rag and asked,
>>
>>
>>
>> "So, Doc, look at this engine. I opened its heart, took the valves

>> out, repaired or replaced anything damaged and then put everything
>>
>> back in; then, when I was finished, it worked just like new.
>>
>>
>>
>> So, how is it that I make $54,000 a year and you make $1.7M when you
>>
>> and I are doing basically the same work?
