> i agree with you, but i don't think you have to go that far to make your case.
I went back and forth on quoting my experience with training and injury above and didn't, but maybe it's worth saying - breaking a few bones in my right hand ended my fencing career, I was broke a tooth training in Krav Maga, and tore some cartilage doing squats with slightly bad form in the gym.
I'd have preferred not to have had those injuries, but I wouldn't give up the lessons I got from my training to not have them, even though all three are a minor annoyance on a semi-regular basis.
Tangential note - I'd recommend epee fencing to anyone here. It's a lot like playing Chess with your body, incredibly cerebral and conducive to excellent thought and flow.
I've never been as locked in as when I came back from down a few touches to tie it up at 4-4 or 14-14... you know that last touch is everything, and your opponent starts thinking "oh no, I could lose this when I was up so much" - in epee fencing, if you have a lead you almost always win, because a draw benefits the leading player and draws are easy to get if going for them - when you come back from a deficit, meaning you're scoring touches and avoiding them getting even a single draw, that final touch you get so locked in, and then winning after being down... nothing else compares. I shiver just thinking about about battling back to even, winner-takes-all... nothing else compares.
