Good posture also helps you breathe better, which can help you feel more energized and concentrate better. Your diaphragm doesn’t work right when you sit hunched over, so your breath gets more shallow.

If you ever need to talk a lot for work or some other reason, good posture is essential so your voice sounds good and doesn’t get tired too easily.

And it helps strengthen your core, which is good for balance and other things.

Maybe it depends on what you watch. I use Youtube for music (only things that I search for) and sometimes live streams of an owl nest or something like that.

If I stick to that, the recommendations are sort of OK. Usually stuff I watched before. Little to no clickbait or random topics.

I clicked on one reaction video to a song I listened to just to see what would happen. The recommendations turned into like 90% reaction videos, plus a bunch of topics I’ve never shown any interest in. U.S. politics, the death penalty in Japan, gaming, Brexit, some Christian hymns, and brand new videos on random topics.
