      From: https://www.bbc.com/sport/61346517

      *Tucker: When boys reach the age of 13-14, things start to change physically and we see increased muscle mass, bone density; [it] changes the shape of the skeleton, changes the heart and the lung, haemoglobin levels, and all of those things are significant contributors to performance.

      Lowering the testosterone has some effect on those systems, but it’s not complete, and so for the most part, whatever the biological differences are that were created by testosterone persist even in the presence of testosterone reduction - or, if I put that differently, even after testosterone levels are lowered.

      It leaves behind a significant portion of what gives males sporting performance advantages over females.*

      So i guess it depends on when the transition happens?

    That looking too closely at the screen will blind you or damage your eyes. This myth originated decades ago in the 1960s from an advertisement by a television manufacturer. Basically in 1967 General Electric reported that their color TVs were emitting too many x-rays due to a factory error, so health officials recommended keeping children and pretty much anyone else at a safe distance from the screen. The problem was soon resolved, but the myth endured.

    If you ask me I would say that x-ray radiation has little to do with going blind, I have no idea if radiation can actually make you blind, but it’s funny how somehow eye diseases got in the way as the only possible consequences in the myth just because we use our eyes to watch TV.

    That by not being ridiculously overtly bigoted, they have actually interrogated and rejected their own bigotry. The former is basic and mostly relies on social conditioning. The latter requires reading history and people who are criticizing things with which you may identify and therefore take very personally. The latter is not taught in school and school does not provide the tools (outside of literacy) to do so, so it’s a difficult, painful, abd regrettably rare thing to see, usually requiring sone trauma to change.

    I always think about when I was taught about taste and the human tongue back in grade school, they had these diagrams about zones on the tongue corresponding to sweet, sour, bitter, etc. like a “taste map”. I’m not sure how many generations were taught about it but turns out it just isn’t true at all. So, not like it’s important but you got a lot of misinformed folks out there in regards to taste lol

      That always confused me as a child, since it was super easy to just test it for yourself. Turned out salt tasted salty regardless of where on your tongue it was, the same for the rest of the flavors.

        Yup I remember thinking to myself at the time that I must be tasting incorrectly or somehow my tongue is different from everyone else lol.

    Nearly anything abouth Pre-Columbian North and South America. Turns out, there was no homogeneous “Native” culture, just as there was no “European” culture. Every different group had their own traditions and stories. They all were complex people, not one-dimensional savages or pacifists. We should simply view them as any other people.

        “Go Vote!” Rings more and more hollow every day we have watch the country crumble. I am begging you to think outside the box of electoral politics because it is where dreams go to die.

        Nobody voted to put kids to work at meatpacking plants and we will almost assuredly not be allowed to vote on a solution but there are children suffering dangerous jobs right now. The capitalists that run the country do not care about your votes they care about profits and they have so many more resources than us to tip things in their favor.

        Voting has not and never will be enough. It is literally the bare minimum you can do and you should not pat yourself on the back for it.

          I assure you I’ve thought long and hard about this.

          Nobody voted to put kids to work at meatpacking plants

          Ah, but they did. Politicians talk about doing that and people still vote for them. That’s the whole problem.

          Voting has not and never will be enough. It is literally the bare minimum you can do and you should not pat yourself on the back for it.

          The alternative is violent revolution. If you’ll study history, you’ll observe that most violent revolutions result in either failure (in which case the revolutionaries are all executed) or a brutal dictatorship that no one can meaningfully challenge (see Mao, Stalin, etc). Very rarely does violent revolution have a result that could be reasonably called positive. The 1776 revolution in what would become the United States is a historical anomaly, and there is no good reason to believe that doing it again would have the same positive result.

                Form a labor union, join a leftist org, start a mutual aid network for your community. Literally ANYHING beyond just mindlessly yelling about voting.

                  It’s pretty hard to form a labor union as long as it remains legal to just fire the entire workplace’s staff and replace them all, and that will remain legal as long as people keep voting for anti-union politicians.

                  Leftist organizations and mutual aid networks already exist in good number, and that’s great, but it doesn’t put good politicians in office. The one and only thing that decides who’s in office is voting.

                  I would like to remind you that if voting didn’t do anything, no one would be trying to stop people from voting.

            How can voters show demand for non-corrupt candidates if their only options to vote on are corrupt candidates? How can we change this?

              There was a non-corrupt option in 2016: Bernie Sanders. Almost no one voted for him.

              How can we change this? Somehow convince all of America to consistently vote for the least-corrupt candidates in both the Democratic primary election and the general election. This will shift the Overton window back to where it should be.

              I cannot fathom why people aren’t already doing this, so I couldn’t tell you how to convince them to start, but that’s what has to happen. Somehow.

    “The human eye can only see 30 [or 60] frames per second.” Truth is, there are some events only 1ms long that a human eye can see, so the real upper limit is [edit: at least] 1000 frames per second. There are diminishing returns, but there is plenty to be gained by getting to at least a significant fraction of that limit.

      The eye-brain system is totally analog. The shortest perceivable events have to do with how bright they are and how depleted the photo-receptors are in your retina. You could see a single 1/1000s pulse in a dark room but a 1kHz square wave would appear to be a continuous light.

      so the real upper limit is 1000 frames per second.

      This is basically the same misconception just kicked further down the road. The truth is that the human eye simply does not see in any way similarly to the way a camera sees and can’t be compared. There is no upper limit.

    WiFi/Cell phones give you cancer. Both devices operated in the microwave spectrum, at or below 1 watt of power. That’s about the same amount of power as the flashlight on your phone but in a wavelength so unenergetic that you can’t even see it. You could put the phone in your mouth and get absorb less energy than just walking outside into the sun.
