Jones has been lucky in that sense that he's had a contract during these terrible injuries - to ease off the financial pain, but that doesn't negate the fact that he's been very unlucky to not be able to fulfill his career and probably had to fight a very long stretch of mental hardness as well. Most these people complaining are probably very young and can't fully get a grasp of it yet, but you should just hope that you won't encounter long-term health issues that includes getting constant medication to pains that can lead to addictions of not so happy kind.
Money doesn't buy you happiness, otherwise you would never see rock stars dying to suicides or overdoses... most complainers here think that just because he was paid well, everything is okay.
I've personally been recovering from a surgery for a year now and it's been very difficult and I've tried to avoid most of the toughest medicine just because of the horrid side effects from the long term use to be able to go back to normal, I can relate a bit here, thing is it would suck as much as it does now even if I was super rich.
