Anyone have a theory to explain how comes so many fighters seems to get sick easily? You would think these guys should have superb immunity since they are in a much better shape than most of us and are young. However, excuses after fight always are about being sick during training. I actually never heard about staff infection before it got mentionned left and right by fighters. Getting skin infection sounds pretty rare to me! Is it overtraining, steroid, gaining and loosig weight? I am clueless!
