One interesting question the video does (re)raise is: why is it that while spears historically did the majority of the "hard work" it is swords that (almost) always get the majority of the fame and attention?
Why there are so few persons interested in learning and mastering a weapon that had such importance in human history and survival (probably there are still persons who depend on it to survive) compared to the number of people playing around with swords.
I suppose it has to be not only to the sword being a simbol of status and thus associated with legends but also due to people being more interested in the flashy/ duelish side on fighting than in what really worked..... That being reinforced by how battles and fighting is usually represented in pop culture (movies, games, etc)
