Do you fight real duels?

I discovered this when I took up fencing in 2001. A reasonable, if somewhat romantic, question. And this answer comes from what appears to be one of the few schools that teach classical, or historical, fencing as opposed to Olympic fencing. The main difference being that Olympic fencing is basically a sport, and if you were to follow its techniques and principles in a real duel you would surely be killed, whereas classical fencing is a martial art, such as would have been practised by young men centuries ago as they equipped themselves for self defence and general aggression.
