I re watched one of Dara O'Briens comedy acts last night and he touched on this. Well I'm sure we all know that not just some but the majority of skills and knowledge taught in the school system (by that I mean high school and lower) turn out to be useless, thus pointless to have learned to begin with. What would you say is the most pointless and useless thing you learned during your time in school or anywhere else? I go with 'algebra'. In what situation am I ever going to need to know the value of 'x'?
