Roller Derby Pain

I have barely survived my first roller derby practice. The problem with being tall...as my good friend Michelle so eloquently put it...is you have farther to fall. My bottom is really talking to me after three HARD falls. I want to stick with this, but a little voice in the back of my head keeps saying that my elevated center of gravity is going to prevent me from being a decent player. One of the veterans advised me to get those padded football player shorts if I don't grow out of my magnificent biffs. If I do stick this out I need to come up with a derby name...suggestions welcome!
