Cutting to the Quick: Sports
There are the obvious reasons of a) they were raised that way, and so they continue to do it for nostalgic reasons and because it's a part of who they are, and b) it gives men an immediate common ground with strangers they might meet at a party or elsewhere, and so you have something to make small talk about for 10 minutes even if the person you're chatting with is a lot dumber than you, it's important to be able to get along with people in these situations.
More importantly, and one of the reasons why professional sports especially took off in the last couple centuries is because men are biologically programmed to live much more exciting, aggressive, masculine lives than most men lead these days. Deep down men still want to be running around a forest, using their skills to hunt down animals and dominate their harems like they were for most of humanity's history, but this isn't really an option anymore with most men working emasculating, subservient jobs and being involved in monogamous, ennui-inducing relationships. So, for 3 hours a day being able to live vicariously through men who are actually still living like men, I propose this makes it a lot easier for men to get through the rest of their shitty boring lives. I've noticed that men who actually still live exciting lives, such as world travelers, African hunter-gatherers, or just outdoorsy types in general, often have no interest in watching sports on TV, and I'm sure the same can often be said of the heads of large corporations and people on wall street, who although aren't out hunting, still live exciting lives, and if they do watch sports it's either just because it's an easy way to relax for a short amount of time with their peers, or in the case of the truly wealthy people in the public eye, it's just to keep up appearances and make the public think that it's a valid way to pass the time if even the best of the best can still enjoy professional sports. In this way, it seems like professional sports serve an important purpose for the upper classes in that it keeps the petite bourgeoisie and proletariat happy/comfortable in their awful lives and thus continue to work their $50,000/year jobs instead of forsaking them completely in order to follow their urges for fun and adventure in a more natural, year-long way, which many people are indeed doing these days.
Come back next week and I'll tell you more ways in which you're wasting your lives, tytyty for reading.
