But later in life, as a source of entertainment, books can't compete with bars, chatting with friends, television, movies, sports, social media,That's just, like, your opinion dude.
All joking aside, I do firmly dispute the quoted statement above. But whether that matters or not depends on a lot of things. I read a lot of books, but also watch television, movies, sports, etc., frequent social media, and chat with friends. And substitute "coffee shops" for "bars" and I do that as well. I don't see it as competition. I like a blend of all of those influences. But I can't answer "why read a book" any more (or less) than I can answer "why hang out at coffee shops?"
So I dunno. I like to read, but I've been reading regularly for something like ~46 years. Reading to me is as much a routine part of life as breathing or sleeping or eating. It would be weirder to me to not read, ya know?
Now if we get away from entertainment and talk learning, then that's a whole different ball of wax. And I hope very little needs to be said about why one should read books if one wants to learn stuff (to use a highly technical term).
The one last thought I'll add though is this: should reading be accorded some special status or significance? Or should there be any sense of shame or whatever in not reading?
There are people out there who would answer an emphatic "yes" to both questions. But personally, even as a life-long avid reader, I say "no". There are a LOT of ways to spend one's time, and only so much time available. And as much as I read, I spend a lot of time not reading. So it's not hard for me to imagine someone with a very slightly different mindset than mine skewing their time allocation towards much less reading. And that's OK. Maybe they are restoring old cars, or volunteering at a soup kitchen, or hunting, or train-spotting, or bird-watching, or hiking, or playing rugby, or doing one or more of a bazillion other things that they find fulfilling, instead of reading. I say that's fine.
