we have to agree that the game is changing and people are getting fitter and fitter. Murray and Dkjo have warrior like body that can withstand hours of tennis. Federer is really doing good job by staying at top with them with less than half the fitness as these guys (in terms of atheletism). It is because of his talent he is still in top 4 not by fitness. I am sure with the kind of training and disciple that Murray and Dkjo have, they will play even close to 35.
