It maybe perception but it seems that the pros generally get sick a lot for people who treat their body as a temple. It seems unusual that Feds and Soderling both got mono. Is it because of constant punishment that they do to their bodies that weaken their immune system? or the designer drugs or supplements that they use? or the lifestyle(ie being with multiple women in many different countries). Anyone out there who have traveled with the tour know? There must be a lot of awareness about this on the tour.
