Although it may sound vulgar and rude, the most underrated skill is prostitution... something that if we think about it, everyone who asks would say "It's easy"... but at some point have you stopped to think about the disgust... displeasure... humiliation... and several terms that would be valid for a job where everyone sees you as an object with a price... that you can touch as you want! regardless of what that human being feels!! many of them exploited by criminal mafias as is the case in South America... people who feel and that the majority did not choose to be there with that job and in that place of the night... If you ask me a skill that nobody considers...
