Although I have no medical knowlege about juggling injuries, I do have some knowlege about experiencing them. I know only too well how frustrating this can be. We all strive to cover new ground and develop new tricks. Each of us has a repitoire that we wish to expand. Unfortunately, there is a boundary on how far this expantion can go.
Physical limitations restrict even the most emphatic desires to learn record breaking tricks.
As athelets, we have a responsability to ourselves not to violate that tool on which we rely - the body. Unfortunately, most of us do not have the athletic physique of an Albert or the natural poise of an Anthony, yet these are the role models that produce the ultimate juggling goals. It is difficult to realize one's limitations and shortcomings. Once these have been realized, it is even more difficult to accept them. It comes down to one simple conclusion.
