Fernando Alonso is showing us that age really is just a number, but for someone who didn't even think they would be racing into their 40s, Hamilton must be getting anxious over whether Mercedes can give him one last hurrah before the curtain does eventually come down.
The year after that deal ends will see a major change to the sport's rules and regulations, with Mercedes likely seeing this as their best chance to put a stop to Red Bull's dominance as the energy drink company will see if their own engine can indeed give them wings.
But Hamilton, who last stood on the top step of the podium at the 2021 Saudi Arabian Grand Prix, might well be getting impatient with a team that was once so ferocious in their pursuit of victory.
The truth is the Silver Arrows now look toothless compared to Red Bull, with teams knowing that unless he made a mistake of some sort, Max Verstappen would go on to win again.
Looking back to the 2021 Abu Dhabi finale – don't panic, we are not going down that road – Hamilton would have scoffed if someone told him he were not to win another race until...well, that's just it.
Where is the Mercedes innovation?
Mercedes have a mountain to climb during this winter break if they are to claw back ground to Red Bull. Yes they finished P2 in the constructors' championship – but their points tally of 409 was less than half of what Christian Horner's team amassed.
From a team that used to be at the forefront of design – remember DAS? – they now appear to be a shadow of their former selves.
Admittedly the 'zeropod' concept could have been a genius gamble, but sadly for the team it saw them fall even further behind.
And let's not mention porpoising again shall we.
So, as Mercedes slowly gear up for pre-season testing in Bahrain, Hamilton will be hoping that the team he knows are capable of producing feats of brilliance will once again come up with some magic behind closed factory doors.
Hamilton might only want one thing for his birthday – the question is whether Toto Wolff and Mercedes will be able to get it.
