I'm getting older now, but I had some "old person" habits even when I was young. When I was in my early twenties I watched the hourlong daily news show on PBS. It was the Macneil-Lehrer Newshour when I first encountered it; now it's just the PBS Newshour.
But whatever it's called it's been the best and pretty much only hype-free, solid, unbiased news source for decades. Most people my age didn't see any appeal, but I was always looking for good sources of information, even if I was going to get drunk and try to pick up girls later that day.
What else? I was there for the first version of social networking: Friendster and whatnot. I saw people building lists of bands and brands and friends and other tokens of taste and identity as a kind of false identity for their online personae. Even in his primitive stage of social networking the fundamentals of it were plain to me, and I was repulsed by it. The phoniness and neediness of it all just repelled me. Zuckerberg was still in high school and I already was done with social media.
There's more, but you get the idea. I was an old man at 23.
