I remember a video of a tenispro episode a few years ago and there he says that he misses his family very much on tour and has no intention of playing until his thirties.
He looked sad there and my thoughts were that he wasn't going to play much longer.
But afterwards he had some pretty good years.
I suppose the emotional issues go up and down and the not so good results lately may make him lose motivation.
Being away from home so much is ok for the younger players, but once they have a family this becomes a dilemma.
All the best to you Luchoman, but I sure hope we get to see you again on tour
