      @Anti - Ethnic Cleansing It can be both :) The nice middle ground in our modern english is "as they like to do" with "like" being that nice middle ground between "something that is preferred" and "commonly done"
      If you have a preference for something, you are also wont (haha) to commonly pursue that thing :)

      @꧁WupperElfe꧂ response to a super old comment here we gooo: it's "as young people are wont to do", wont is not the same as want, though they are pronounced the same. Wont means -> a person or person's particular habit, or a customary behavior. So it is ye olde english way of saying "as some young people commonly do with grapes"

      Nah, I never did such research. I was only 16 years old when I became a vegetarian, and my entire focus was school and boys 😄 (and I still have never done such research 30 years later lol).
      I don’t remember craving chocolate either when I gave up meat. I know that I craved sugar though when I quit smoking years ago, to the point that I gave myself cavities. I don’t know why I craved sugar so much then though. Maybe it was giving me some sort of dopamine rush that I was formally getting in cigarettes?
      I’ve never liked seafood from day one, so I’ve never had any such habit with that. I’ve never been the type that eats a lot of salads either. I love vegetables, but when I eat a salad, it tends to take me a lot of time because I like to put a lot of stuff in it, so I end up not making them very often.
      Being a vegetarian is super easy (it is veganism that requires doing research to make sure you are getting enough nutrients)…
      As long as you aren’t eating garbage, you won’t have any problems getting all of your vitamins and minerals as a vegetarian.
      When my body has some sort of craving for iron, that is when I usually find myself making eggs. That will come in spurts where sometimes I eat plenty of eggs, and other times I will go a long time without eating any.
      Like I said earlier, I stopped craving actual meat six months after I cut it out of my diet, although I will have cravings for a few of different meat substitutes I like sometimes (it’s only three that I like… MorningStar Farms fake sausage patties/links, their fake bacon, and Trader Joe’s fake ground beef, which doesn’t really taste anything like real ground beef at all).

    • AtarahDerek
      AtarahDerek 3 months ago +1

      @Anti - Ethnic Cleansing A craving for meat is typically a craving for red meat in particular--meaning what you were actually craving (more likely than not) was iron. You may have also had a lot of chocolate cravings at the time. If you put a lot of research into a vegetarian lifestyle before switching, you learned to include lots of dark colored and/or cruciferous vegetables, which are high in iron. If you did that, then it was consciously choosing iron rich foods that cured your craving for meat. People who are addicted to red meat, but want or need to go vegetarian (e.g. people with alpha-gal syndrome from a tick bite), may struggle much more to make the transition because iron rich veggies also tend to be less popular, meaning people don't want to eat them, and thus they continue to crave the nutrient they lack in the food they know provides it.
      And if you're a seafood addict, then you may be deficient in iodine. This means you're at risk of thyroid illness and need to actively supplement your iodine.

    • FreeHomeBrew
      FreeHomeBrew 6 months ago +1

      @Anti - Ethnic Cleansing It's funny you name it "gut feeling". Reminds me of that remark I read somewhere that your guttural bacteria may actually influence what you eat based on _their_ needs. This was related to a story about bad food (lots of sugar, fried stuff) and how if those bacteria crave that, they'll somehow make you crave it as well. So if you starve them of what they need, you'll lose those cravings too.
      As for nutritional needs, these vary from person to person. I feel much better being on a high meat diet. The bits I don't like I cut out and feed to my rats. They'll not eat it if they don't like it either.

    • Anti - Ethnic Cleansing
      Anti - Ethnic Cleansing 6 months ago

      Well it was explained in this video that cats do have different sense of taste, as in much less taste than humans. Just sayin’.
      Side note: I used to crave meat because I was raised on it. Then I became a vegetarian at age 16 and stopped craving it after around 6 months post quitting it. The thought of eating it actually began disgusting me (and some meat even disgusted me before I quit eating it - I would be picky by cutting out veins and tendons and got grossed out by a Carl’s Jr hamburger as my last final straw for when I gave it up). I’ve never had any nutritional deficiencies in the 30 years since then, so idk if your gut feeling is a universal reality.

      @Katie Kane You’re right about the grain. I feed Floozie grain free, high quality kibble. That makes her poos hard, so she gets 1/3 can of wet food every day and that helps with the hard poos and she thinks it’s a treat. Vet said to add more water to it, which really helps too. Floozie’s so furry can’t see the pink eye, lol. Princess Fluffy Butt is her nickname.

      @Katie Kane In reality, it's a remnant from kittenhood. Mama cats have to stimulate their babies to go to the bathroom by licking them and just like when they knead you, it's a sign your cat thinks you're their mama. So congrats: you are cat mom!

    @4:29 and @5:39, the key to understanding why the domestic cat's eyes are vertically thin and then go large round like that is "Depth of Field" in relation to "Aperture/Pupil Size". A wider pupil size in a certain direction yields a tighter Depth of Field (DoF). So, when the pupil is thin horizontally, then horizontal edge features (like vertical blades of grass or vertical lines) over a long range will be relatively in focus (let's say objects 2.0m out to 20m for example). When the pupil widens, then the DoF shrinks and only objects within a certain range will be in focus (like 8.0m to 12.0m). So, the cat's eye can use this along with varying focus with its crystalline to gather more info to pinpoint distance.

      One time a single house cat drove an entire species of bird to extinction. They were Native only to an island with a lighthouse and the keeper got a cat. Soon after all the birds were gone. Genocide Kitty don’t give a shitty.

      I own my cat, she brings me silverware, retrieves balls and birds, sits, stays, rolls over, comes when I call her, and goes into her kennel when told. Yall just don't know how train your cats. They take advantage of weak people. She's a Labrador breed.

      @CSN My cats were killing machines out the gate, tho not from breeding, they were pretty standard red mackerel tabbies (a little longer/taller than average, but not to Maine coon size) and they developed their hunting skills cuz they were left on a woman's porch and she decided since she already had dogs and small children she couldn't let them inside. She put out water dishes and cat food and put out the word that she had cats needing to be adopted, but since they had to stay outside they got very used to supplementing their diets with fresh kill. Which they 1000% continued once we took them home.

    I have read that lions' vibrisses receptors are sensitive enough to locate the space between the trachea and the jugular vein in order to bite without spreading too much blood and to bring the prey to a quicker death, saving energy.

    Fun fact about eye rotation. Our eyes do this too.
    Its just hard to notice because our pupils are round. But if you focus on the pattern of the iris, or a vein on the sclera, and have someone tilt your head, you can see the eye remain at level.
