  • I don’t need glasses. Haven’t had my hearing tested, but I think it might be better than average. I can hear high frequencies annoyingly well, 20kHz or a little more (checked with a spectrum analyzer). It’s fun to listen to the high harmonics in music. Vacuum cleaners and electric cars are less fun.

    I can usually hear my muscles and bones moving. It’s very quiet and low frequency, and the muscles rumble. I can usually tune it out though.

    Hearing is a backup sense.

    That might vary by person, but for me it’s not. If I had to pick between being able to see and being able to hear, it’d be hearing, hands down. Being able to see is amazing and I’d miss it, but hearing is just a whole other dimension.

    Being able to know how someone is feeling, just by hearing their voice. Listening to music and hearing all the shapes, colors, and feelings that come with it. The colors aren’t always ones you can see, like blue or yellow. It’s hard to describe. I’ll close my eyes and just listen at a concert (not the whole time) and same with TV, a lot of times. I usually remember it better that way.

    If I have to find something in a backpack, I’ll often do it by feel. I probably look like a raccoon washing its food, but it just works for me. You can tell things apart by feel and sound.







  • Many whale species feed in the depths of the ocean where prey is plentiful, but where the water pressure is immense. At depth, says David King, a chemist at the University of Cambridge in England, many whales find that “their orifices are jammed shut.” So, to properly relieve themselves, they head toward the surface, where their defecations bring a steady flow of nutrients—such as iron, nitrogen and phosphorus—to a part of the sea where they’re typically in short supply.

    Interesting. I never thought about how whales poop before. I wonder how critters that live at the bottom of the ocean do it.



  • 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.
