Papercuts and hangnails do me in. Once the sweat gets in there, my eyes tear up and I want to crawl into the fetal position, but I grit my teeth and push through

Seriously, though, I have a couple of old injuries from mountain biking and such, and a bad left knee that bothers me every now and again. I don't know if it's just me, but I don't mind playing kendo when it's just a muscle soreness from being used - however, when I feel joint pain or something that just isn't "right", I take it easy until I feel stronger. Instead of kendo I'll do some bicycling or even just go for an easy walk with my wife. I don't mind playing with some discomfort, but I draw the line at pain . . . I want to be a nimble 70 or 80 year old, after all
