OK...an example of 'overdoing it'.......this spring i got playing soooooo intensely,...that i was playing nearly 6 out 7 days a week. After a few weeks of this,...i was playing a match....and in that last fateful match i actually stumbled and fell to the court going after balls. (i suspect fatigue showing on me). In the second fall i took i broke a bone (fibula) in my right leg. Been sitting out the last 5 weeks. i chalk this up to 1.using crosstrainers instead of respectable shoes,....and....2,...Not allowing myself to recover enough between matches,...and grinding myself down. The passion is great,..but i let it get the better of me.
