An expert on cars or a certain system from a car. I have seen people who whine and scream about a little noise coming from the exhaust or from the motor or they feel the car lurch once in a while, and i never notice it. These people suffer immensely because they are annoyed by a little noise that means nothing. And no, their car never breaks down, but they just hate the sound it's making.
And many other examples too of hobbyists and anal-retentive Obsessive Compulsive souls who go thru life miserable because they know too much. Are we better off not being experts?
