To take care or not to take care in the question!!

to take care or not to take care is the question. Injuries have been a great concern for tennis professionals these years. Be nadal with his knees, nalbandian with his hip, federer with his wrist or Safin's shoulder. The options they have i feel is to take care of it and continue to play for 2 or 3 years and then retire or take proper care and a break from tennis then come back to play good tennis for the next 4 to 5 years. Anythin u would like to suggest
