       | It's an interesting premise, but I am not at all convinced by
       | this paper -
       | 
       | The author comments "I tried to carry out surveys to collect
       | evidence but they were meaningless, as tribespeople give you the
       | answer they think you want", so this is in no way a scientific or
       | quantified study, just the author's own observations.
       | 
       | The only citation in this paper is for the fact that humans are
       | one of 200 kinds of primates; I really wish there were some
       | actual citations for the really fundamental assumption here that
       | the "forest dwellers and nomads" have fewer musculoskeletal
       | health issues compared to "civilised people" (in the authors
       | words).
       | 
       | Additionally, the photo selection here is kind of uncomfortable -
       | starts with a Kenyan human compared (similar) to a gorilla, and
       | then is mostly photos of the author himself in only his
       | underwear.

         | Also, the photos of the author in their underwear is to make it
         | clear to the viewer about the positions being demonstrated.
         | 
         | Also, the backstory of the author was that he was in the army
         | (before he got blind), and spent time with people from Kenya
         | then. Thus, there is likely a focus of a person from Kenya in
         | this photo. Also, it is about finding people who are not the
         | ones in developed countries sleeping on modern era invented
         | beds and beddings.

         | It's easy to do since we just get handed a headline and a
         | nih.gov link that presents the work no different than a study,
         | but you're evaluating it on different criteria than it was
         | written or published for.
         | 
         | It's a discursive, exploratory essay published to the BMJ by a
         | working/clinical physiotherapist to share some intuitions
         | they've developed from reflecting on personal and clinical
         | experiences.
         | 
         | The journal it was published to has many different forms of
         | work that it shares, clearly indicated in format and heading,
         | selected by their assumed value to other professionals in the
         | field.
         | 
         | The person writing this probably did not believe they
         | established scientific proof of sleep postures, nor would the
         | editors or readers who encountered the article in its original
         | form have thought such a claim was being made. It just would
         | have been an interesting perspective to think about, maybe,
         | before moving on to another article in the journal.
         | 
         | 22 years later, it's interesting how we've gotten used to
         | ignoring context and judging everything by one criteria. Some
         | of that's probably due to efforts to normalize information as
         | "data" with a predetermined schema so that it fits nicely in a
         | database and only needs one stylesheet.
         | 
         | It's kind of a shame, though, because it makes it a lot harder
         | to appreciate things as they are, because we get so caught up
         | in seeing them as a poor version of something else.

           | This is good context, thank you.
           | 
           | I do find the ideas interesting, but ultimately frustrating
           | because of no grounding in anything that I feel like I can
           | trust - e.g. is it actually true that "non civilised" groups
           | have fewer back problems?
           | 
           | But in a context where this author is known and trusted, or
           | that is explicitly open to hearing observations based on
           | experience without requiring any kind of citations or
           | scientific studies, then I can see the value - I wish that
           | was communicable here somehow, rather than looking like a
           | regular peer-reviewed journal article.

       | "If you are a medical professional and have been trained in a
       | "civilised" country you probably know next to nothing about the
       | primate Homo sapiens and how they survive in the wild."
       | 
       | But what is "wild"? Consider:
       | 
       | https://books.google.com/books?id=LXmY3Q8qBngC&pg=PT74&lpg=P...
       | 
       | "Homo heidelbergensis (700,000 to 150,000 years in Europe and
       | 600,000 years in Africa)... were probably the builders of one of
       | the oldest known types of constructed habitations found so far,
       | at a site called Terra Amata in southern France. Several large,
       | oval structures, 7 to 15 meters long and 4 to 6 meters wide, date
       | back 380,000 years."
       | 
       | So it is possible that humans have been living in nice houses for
       | 380,000 years. And who knows what sort of beds homo
       | heidelbergensis slept in? It's possible humans have preferred
       | comfortable beds for a long time. Who knows? We have not (yet)
       | found examples of bedding from that long ago time period.
       | 
       | Conclusion: be wary of anyone who makes assumptions about what
       | constitutes "wild" in the modern context.

       | Hmm what. That doesn't sound possible.

           | The most remarkable part, mentioned in the article, is that
           | the mouth/jaw closes naturally. Very interesting because my
           | mouth naturally hinges open when I sleep on my back (or on my
           | side with pillow). Given the many benefits of breathing
           | through your nose (vs mouth-breathing), I am going to give
           | this sleep position a try for a few nights. Each body is a
           | little different and I enjoy n=1 experiments.

             | You are right. I sleep on the sides but with pillows, and
             | suspect I am a mouth breather too. But if you don't use the
             | pillows, the mouth does naturally remain closed. However, I
             | am still sceptical about this as without the pillow to
             | support the head / neck, I think breathing is bit more
             | laboured. Moreover, in my experience, sleeping on the side
             | puts a lot of pressure on your neck and shoulders and you
             | often wake up with sore muscles in those parts of the body.

       | getting used to, the chances are it'll be nice to your bones,
       | 'cause evolution didn't know about soft beds, just hard ish ones.
       | The older I get, the firmer the bed I need seems to get.

         | Yeah, I prefer sleeping on the floor now with a thin mattress.
         | Great for the back.

         | Keep in mind there is a broad spectrum of human bodies around.
         | Evolution also didn't intend for the average male human to
         | weigh almost 200lbs. Softer beds may be a response to joints
         | that have to support a lot more weight.

       | Btw: people also invented hammocks (somewhere in South America).
       | 
       | Hammocks are really comfortable, why comparing beds with sleeping
       | on the ground? What's the point?
       | 
       | Maybe to be able to tell something like "primitive people and
       | gorillas know instinctively how to sleep on a hard surface".
       | Really?!
       | 
       | Try by yourself, there is probably not much of a choice, sleeping
       | on the ground is uncomfortable in almost any position but few.
       | Tired enough you will figure out.

         | I think the benefit of hammock is above all to avoid all kind

       | attention to correcting postures and strengthening posture

       | posture corrections, most musculoskeletal pain reoccurs. There
       | needs to be more scientific research on Alexander's Technique,
       | Pilate, and ayurvedic massage therapy (that many in India swear
