  • This study analyzes historical results of three different man versus horse races (in Wales, in Virginia, and in California). The data shows that human performance decreases with temperature, but less so than horses, so that 30°C is approximately where the best humans can start outperforming the best horses that year.

    I would think that even with 15 minutes of intermittent pauses/checks, that time is still productive for cooling the animal and would add less than 15 minutes to the theoretical total if they were allowed to run the whole time.




  • A lot of young people don’t realize just how difficult post-school dating was before online dating. Once we exhausted the pool of 5-10 single people who were friends of friends, that was basically it. We’d have to go find strangers at the bar.

    That conditioned everyone to be slightly more willing to settle for less perfect matches, knowing that there wasn’t necessarily a replacement available. That could be a good thing (people more likely to have the patience to let a spark develop) or a bad thing (a higher percentage of couples who just resented each other).

    I can see an argument that things were better before online dating for some subset of people. But having lived that period, I can say from experience that it wasn’t easy then, either. And for someone like me, who is a better writer than I am a speaker, especially over the phone, the rise of text-based communication was helpful for navigating the early stages of relationships when that became the norm.

    It’s a few things that stem from bipedalism:

    • We can run and breathe entirely separately. Most quadrupeds lack the ability to run and take breaths independently of the pace of each step. Watching cheetahs sprint, for example, show that they have no choice but to exhale every time their legs come together and inhale every time their legs push apart.
    • Running on our hind legs only frees up our hands to be able to use tools and weapons, maybe even water containers for drinking on the go.
    • We can see further by standing up, and can make tactical decisions based on terrain, while still running pretty much full speed.

    Combined with our unusual ability to cool ourselves by sweating, this gives us an advantage over pretty much any animal in the heat. Wolves and horses can still outrun humans in the cold, but lack the cooling mechanisms to maintain pace in the same heat that we can.


  • I still use reddit.

    Lemmy is still missing a few things:

    • Sports discussion. There’s nothing quite like the absurdity of some of the sports communities that really brightens my day, from really deep analytical insights to the dumbest meme jokes in existence.
    • City-specific local discussion. I still spend time on my city’s subreddit, which helps keep me tuned in on local happenings.
    • Non-tech related career discussion. My field (law) has several subreddits useful for talking shop, growing careers, making fun of shitty lawyers, etc. That doesn’t really exist here.
    • Hobby discussion. I’m trying my best to participate in fitness and weight lifting related subreddits but there just isn’t a critical mass of commenters to get a discussion really going. Plenty of my other hobbies and interests are missing here, too.

    I’ve deleted the reddit alts I used to use for technology related topics, parenting/relationship topics, political discussion, and stupid general purpose humor or memes, as Lemmy has enough of that I don’t need Reddit for those topics. But for the ones I’ve listed above, I’m still using desktop “old” Reddit.

    I’m also still on Instagram, but only follow people I know personally. It’s the easiest way to keep up with my acquaintances’ lives: who’s marrying who, who’s having kids, where people have moved, etc.


  • It’s because we’re also very used to seeing photographs of a subject in shade while the background is in full sunlight. If you take a picture of a white and gold dress in the shadow of a patio, with the background all fully lit by bright sunlight, the actual pixels representing white objects in the shade would be that bluish gray tint.

    The problem here is that the dress isn’t in the shade but those of us who see white and gold simply assume that it is in shade, while black/blue viewers (correctly) assume that it is under the same lighting conditions of the overexposed background.
