> It seems most people today have headphones on all the time. I don't understand it. I'm not sure, but it would seem people hate their own voice?

Depends on the location maybe too? I think in big cities I see more people with headphones on when they're out and about (which makes sense, cities tends to be noisy and not in the interesting way like nature is), compared to in the small town I live in now, where most people aren't wearing headphones, except if they exercise.

I guess it also depends on what you listen to. I've found certain types of electronic music to essentially put me in a "trance of focus and clarity" and as long as I keep it going, that can give me enough energy for hours to do all the chores of the day + end it all with a swim, all while listening to liquid drum & bass and forgetting about everything else in the world.
