This is an interesting topic that Sword Chick and I were discussing recently. Sorry if I'm stealing your thunder, Sword Chick! But I though this would be good to go ahead and post so we can discuss it.
The question is, what would you have been during the medieval period? What line of work would you have had? Would you still have been a soldier, knight, mercenary, or anything at all involving swords and armor?
Obviously it would have a great deal to do with what you were born into, in terms of class, and family trade.
But one of the things that makes this question interesting is the large number of technical people (and geeks in general) that are drawn to swords and historical swordsmanship. A deeper question might be why is that the case? For a lot of folks, their interest in history (or fantasy) has a lot to do with an escape from the mundane modern life. Perhaps if they lived during the times of our studies, these things would also be mundane. And add to this the fact that most techies and geeks don't consider themselves to be the least bit athletic, and yet in medieval times, it could be argued that jousting and tournaments of the knightly class were the epitome of athleticism. Swordsmanship and other combat skills are certainly athletic skills, and ones that would have been highly valued. And being less athletically gifted could cost you your life.
So where does the geek fit in? Having strong technical or artistic ability might have lead one to work as a carpenter, blacksmith, glassblower, or any number of other trades. Or perhaps, if they were to be involved in a military career, they might have done better as a tactician than as a soldier.
Statistically, we'd probably all be peasants. But ignoring that, what do you think you might have done for a living back then? If it's not military or combat related, what else and why?
I'm not sure I can answer that, in my case. I'd have done well in technical trade, no doubt. But would I have been a knight or man at arms? It's possible I'd have been repelled by the "mundane brutality" and sought something else, but I don't know. I might also have been drawn to it, as I have been today.
