injured

So I don't know why this year of COLLEGE LIFE is so full of injuries. About this same time last year I twisted my knee. This wasn't anything serious, it was simply a pulled/tweaked ligament/muscle or whatever it was qualified as. Then, last may I tore my hamstring and was on crutches for five and a half weeks. So, needless to say that injury was a bit more dramatic. But just this last weekend I twisted my other knee. I don't know what's wrong with me because I used to never injure myself and in just a year I have three times. My sister says it might be because I am double jointed and pretty flexible so my joints aren't as protected or something along that nature. So basically there's nothing I can do about it. Well I guess this gives me more reason to be lazy.
