I guess part of the reason I think about it quite a bit these days is because almost all of my friends who are my age and older have mostly stopped. The guys who haven't are the ones who are still single, living by themselves with no responsibilities to anyone beyond their employer.
One guy I know has vlogged and blogged quite a lot about his experiences "quitting" video games. The realisation he came to was that gaming was holding him back in many other areas of his life, and that he had been reluctant to acknowledge this earlier in his life because he was scared about what that said about all the time he had sunk into video games instead of solving his problems. It's not that severe for me, but I do wonder whether it's a hobby I maintain out of laziness/fear of trying something new, rather than because I still love it.
I'm very happy for Jegat, he deserved a bit of luck after trying so hard for that Top 10 all Tour. Those lesser GC guys often don't get much attention but I respect that they go through a similar grind as the top guys on every climb to minimise time gaps when a lot of other riders around them are taking it easier. I didn't think O'Connor would care about a Top 10 considering his goal was a Top 5 and he'd already won a stage, but the fact he chased by himself at the front of the peloton suggests it meant something to him. Hopefully he gets a proper GC support team next year. I know Jayco were down one and Schmid crashed while leading the peloton, but it's really quite poor that their team was so weak O'Connor had to defend by himself.
