This is just my PO but
1- I do know for a fact that those plane flights across the world are killers, Yes! even in first class, even on your own private plane...I don't care they are horrible.
2- That is his real face, plus stubble, plus he does not exactly seem like a happy go lucky kind of guy, could be his demeanor.
3- Here again and this is just my opinion BUT, if he did/does have some kind of substance abuse issue, maybe just maybe he is trying to get his life in shape and when patients are "kicking" or trying to do what is right, for a while there, it is horrible! and they feel sick, angry,...you name it they feel it. For sure not much desire to smile and be jovial.
I speak not as a fan or connoisseur of his work, nor of his affairs with ladies, because I do not care. Also the only one who can tell who he is happiest with is himself. BUT if correct I honestly do hope and pray that he is able to overcome whatever malaise he has, be it physical or emotional and that he is soon in a good place in his personal life.
I wish them both the best.
