As a thought experiment, jumping back to the parallel with fitness, is your statement the same as saying "I suppose it depends on the person, but the older I get, the less patience I have for eating healthy and exercising, and the more I'd rather focus on eating food I like and spending time on my sedentary hobbies."? As in, it's 100% your choice to live your life that way, but you also have to accept that there are health repercussions associated with certain life styles.
Side note: I'm not sure what you mean by a "fake" social gathering. But for me, I've been taking part in a debate society, and some French meetups lately to socialise more, and I've loved it. Everyone is genuine in that they're there for a specific shared interest. And I've found that my thoughts/ideas are greatly improved from the ability to debate with others. Sometimes I'll realise I have a huge blind spot, and need to reject an idea. Sometimes I'll realise my idea had a short coming and that it needs to be adapted. Either way it just improves my thinking.
