Lewis Hamilton has been told to make sure he is ready for Formula 1 retirement before he finally decides to walk away.
The seven-time world champion is 38 years old and will have celebrated another birthday before the start of next season. And his current Mercedes contract has less than six months to run.
But his intention is to put pen to paper on an extension. That's despite previous assertions that he would not still be racing in F1 beyond 40.
