Mine‘s getting so accustomed to cold showers that I a) absolutely do not mind cold water for swimming etc. anymore and b) could not enjoy warm or hot showers anymore. They just weren’t nice at all.
As compulsion, I watch YT tutorials at breakneck speed: 2.5x-3x.
YouTube tutorials can be pretty low information density. Sentences have important pointers every 5 seconds or more ("The thing is, like, if you're trying to do this, or this, do X first" -- predictable/less functional words), and the first third of a YouTube video is often useless. Of course, denser videos get slowed to normal and have clips replayed.
Internally, this stems from nervousness of wasting time (oops), and it hurts my head if I do it too long ( but looks cool beforehand B) )
Tutorials I might need to go a bit slower, remembering broad strokes isn't enough, and detailed steps in order is probably too much, but that would be true at 1x speed as well.
For videos generally I watch almost everything at 2x or higher. Headphones help, it would be much harder if there were any competing audio stimulus. If I'm forced to go at 1x I retain almost nothing.
