I'm thirty six. Pretty sure that's not 'young' by most standards here, judging from what I've seen of the populace.

Various weaponry. Some traditional--swords, staves, bows. Some modern, at least from my point of view: various types of guns, explosives, that sort of thing. Other hand to hand techniques besides the martial arts, a lot of which deals with using whatever tools are at hand. Other things that aren't necessarily related to fighting, but part of the taught skill sets.
