Meet three eminent heart surgeons: Dr. Michael DeBakey (center), Dr. Christian Barnard (left), and Dr. Adrian Kantrowitz . These guys are medical pioneers. I wonder if they all hung out together on their time off. There is a brotherhood/sisterhood among cardiologists. They routinely save lives, and I think that experience draws them together into a tight community.

My mom sent me this email about a cardiologist, a mechanic, and a car engine. Enjoy reading it, and have a nice weekend.

A mechanic was removing a cylinder head from the motor of a Dodge SRT-4 when he spotted a well-known cardiologist in his shop, who was waiting for the service manager to take a look at his car. 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 SRT.

The mechanic straightened up, wiped his hands on a rag, and asked, ‘So, Doc, look at this engine. I open its heart, take the valves out, repair any damage, and then put them back in, and when I finish, it works just like new. So how come I make $39,675 a year, a pretty small salary, and you get the really big bucks, $1,695,759, when you and I are doing basically the same work?’ The cardiologist paused, smiled, and leaned over, then whispered to the mechanic

‘Try doing it with the engine running.’
