“Within every man’s brain, there is a system of alarms that are designed to go off in any situation that would place the man in danger. When you walk on railroad tracks, it tells you, “Get off the tracks.” When your neighbor’s pretty young wife locks herself out of her apartment in her underwear, and comes to your apartment, asking to use your phone, the alarm goes off, telling you, “This looks bad.” (you let her in, of course, because a bigger part of your brain says ‘This looks very good’)”
