So in my story there are three fugitives trying to escape a dystopian country. I'm thinking of having them all know parkour. In this digital tech-heavy world, they are actually very minimal, not even using a cell phone half of the time. It takes place about 90 or so years from now. So technology has obviously improved since today. I'm also thinking of also having them carry and wield weapons. Before this parkour idea came along, I thought they would wield shotguns, assault rifles and stuff, hell even the MC uses a machete. But that might get in the way, so maybe they could stick to just pistols, knives, or other smaller weapons. But would that also get in the way for if someone were to know parkour? And what age is earliest for someone to learn parkour? 14?
