Heart surgery

A mechanic was removing a cylinder-head from the engine of a
motorbike when
he spotted a well-known cardiologist in his garage. The
cardiologist was
there waiting for the service manager to come take a look at his
bike 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 motorbike. 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 £25,000 a year and you make ten times
that, 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."
