Roger Federer [VIDEO] won't be around forever, at least when it comes to playing professional tennis. He may have been on a winning trend lately, but, like any good thing in life, this current situation is not something to comfortably sleep on.

Now 36-years-old, Federer has made huge progress in extending what was already an astonishing career. Winning three out of the last five Grand Slams surely helped his cause. Last year was all about Federer's surreal output of tennis.

And, many didn't have the chance to acclimate to his surge.

It was indeed one of the most shocking yet amazing comebacks in tennis history, and the act alone opened the door for maybe some unrealistic expectations.

After all, there have been voices talking about potential Clay Court action for Federer which is a bit far from his safe zone.

A crucial part of the season is about to start

Roger Federer did well by going after the world's No. 1 spot in Rotterdam. It certainly helped him finding closure after having a huge run over the past twelve months or so. Now, Federer will start that usual grind of professional tennis meaning that he will engage in defending the Sunshine Double success of last year.

It seems that luck enjoys staying on his side as many of the top names are out due to injuries. Rafael Nadal and Stan Wawrinka completed a long list of absentees from the first Masters 1000 of 2018.

To retain the No. 1 ranking throughout the clay court season, Federer must win the title at Indian Wells or at least reach both semis there and at Miami.

Way past his prime years, Federer [VIDEO] has become the oldest player ever to hold the top spot in the ATP rankings. More than fourteen years after having his first stint at the summit, an all-around player returned to steal the show.

We should enjoy it because it won't last

Taking a look at the current rankings might give a false sense of security. Assuming that Federer will survive the Sunshine Double challenge, it doesn't mean that he is off the hook. The grass season plays a crucial part of his schedule too with back to back titles in Halle and Wimbledon to defend.

A potential lay off on grass would stir things up. Moreover, the success Federer had back in 2017 was not the only time he did well. He did great things even after the US Open. Two more titles in Shanghai and Basel are there as a consistent burden to carry around.

Roger Federer has been providing us with mesmerizing tennis making it easier for us to forget that he's a human too. Age will have the final word when it comes to this inspiring story.
