Hi Johnny C. and others,
Johnny, I'm pretty sure that peeing blood after lots of hard playing has nothing to do with straining our kidneys.
I've also heard that explanation, but it just ain't so.
We don't play with our kidneys - red blood cells get popped in the blood vessels in our hands during lots of hard playing, and the dead blood cells are expelled through the urine - this is what causes "peeing blood".
If blood is peed often, it's bad news. Like I said, anemia is a weakened conditon of the bloodstream. The red blood cells contain the iron, so anemia can also mean iron-poor blood.
But there are several kinds of anemia, some hereditary and some brought on by lots of high impact where red blood cells are broken, as in boxing, or as in over-hard hand drumming.
Sure the old masters' playing is anything but "anemic", though it's also true they don't hit as hard as they did when they were younger. And for good reason.
If anyone pees blood after lots of playing, I recommend lightening up the touch, learning advanced techniques like double rolls instead of singles (doubles are faster and lighter) and in performance making sure you are WELL-MIKED so you don't have to hit as hard.
It's possible to play intensely without going nuts in volume and breaking too many red blood cells.
All the best,
yoni
