Why do so many shadetree mechs jump into the engine bay after a successful removal? Let's examine the psychological reasoning, as hypothesized by Dr. Sigmund Freud. You see, the empty engine bay is a natural proxy for the womb.
There's no substitute for the feeling of accomplishment after rolling that engine safely away on a rickety, Chinese-made stand. Of course, that gaping maw of the engine bay just begs for climbing into, while your work buddy grabs a snapshot of you sitting in your own "lost paradise."
According to Freud, it's a matter of regressive compulsion, or a human desire to return to this "lost paradise" of the womb. For Freud, this—a continual drive toward equilibrium—represents a "continuous descent toward death," where death satisfies a longing for resolution and quiet and an unconscious flight from humanity's pain and desire.
It's from this drive that Freud conceived the "nirvana principle"—the urge to return to the nirvana of the womb—which becomes for Freud "the dominating tendency of mental life."
And that's why all the photos. Our time's about up.
