Short answer: yes—Wikipedia: Artistic Roller Skating. I’m guessing your country’s governing body (e.g. USA Rollersports) could direct you to some if you were interested.

No comment on headphones vs. not; I’d never even heard of it until this post, but I found some free audio for people in the same curious boat: Binaural Beats

You can, but you may have to bounce around servers a bit to find one that works. I’ve had good luck with servers in Norway (not 100%, but better than other countries).

I did my first cables on the Northward Hat from Tin Can Knits. Free pattern, super simple, knits up fast, and you get to give someone a fancy hat!

I don’t know about ”most people in the workforce.” I’m in my mid-30s, and not only do I remember it once or twice from my childhood, I also encountered it once in 2013 (at a brewpub somewhere in New York). You’re right, though, that it becomes less of a thing with each passing year.

I frogged the majority of a piece recently, and I felt better when I reminded myself that I like knitting. I don’t care a ton about knitted things. So I got to have all of that fun and learning, and now I get to do it again without even buying more yarn. (Mine was also on my only long circular, so now I can magic loop again. Double win.)

Also, it’s a beautiful piece, so go you. I actually dig the colors.
