In case you're lucky enough not to know this yet,
by 30 you may be starting to lose a step but that's all, still able to play prime tennis.
by 40 you've lost more than a step and only the amazing can still compete at the top level, think Gonzales and Rosewall. In fact Pancho once said that the eyes go before the legs.
by 50, it's over for everyone, you're not anywhere near the player you once were, no footspeed, no more quick hands and no eyes. You're losing strength but at least new racquet technology has helped here.
Amazing Mac can still be on the same court with him.
