The planet may be warming, but a recent study indicates that mankind is going the other direction.
Researchers at the Stanford University School of Medicine have established that people's bodies are now typically cooler than the textbook figure of 37C, first established by German physician Carl Reinhold August Wunderlich in 1868.
The study shows that modern-day men have a body temperature 0.58C lower than their 19th century counterparts, while women's are 0.32C lower.
This decrease has been attributed to "changes in our environment over the past 200 years, which have in turn driven physiological changes". However, the study acknowledges that establishing cause and effect remains "inherently unprovable".
The rate of decline is about 0.03°C per birth decade. Body temperature is a marker for metabolic rate and could partially explain changes in human health and longevity over time.

Over 100 years or so, there is supposedly a heavy trend of getting less and less daily calories from fat.
A high fat diet turns your body into a furnace. Eskimos eat the blubber to achieve this. I am by default skeptical about science. I did it on me and it turned out to be true (but n = 1). You can test this yourself, the effect is very fast to observe.
This is yet another example of the generally broken science process nowadays. Here specifically: the fact that scientists do not sufficiently read prior art before trying to publish something, the fact that they do not seek to apply Occam's razor principle systematically, but so many more problems like the ridiculous threshold for declaring a result statistically significant, the lack of mastery of technology developed by others, the lack of mastery of statistics, the fact that the principle investigator is all too often actually just a professional grant seeker and master of getting published with trendy buzzwords and not rigorously validating the work of his young servile scientists horde. Been there, done that, only as a young servile scientist though.

You seem to be a good scientist then. Working in academia, I can confirm that most of your criticism holds true, it is a social process after all not primarily dictated by scientific thinking let alone a rigorous thinking process. From a meta-perspective, you do not have to be as negative though. The wheel gets reinvented all the time, this way all areas get some love again after being forgotten for so long (that is very similar to how fashion works). This in turn brings old ideas into the current context which can leads to new things (neural networks, anyone?).

They're busy reinventing the wheel, sure enough. Machinery has to be greased, if you expect it to last. Or, I should say "lubricated", since there are many lubricants besides grease. Anyway, Arburg has reinvented the grease nipple, or alamite, or grease xerk. They give you a stupid little indentation on the equipment where the grease is supposed to go, and a little tube that you insert into that indentation. Push a couple of times, and grease is supposed to flow. Supposed to, anyway. I've found almost-but-not-quite the same indentation on the new robots as well. Except that indentation isn't quite the same as Arburg's. So now, we have two new "grease guns" which are only good for those specific pieces of equipment.
The purpose of these reinvented alamites? It can only be early failure, because you just can't push grease through them very well.
Given the opportunity, I'll drill them out, tap them, and put proper alamites in them. But, my half-witted boss won't hear of it. "They did it like that for a reason!!" I'd love to stuff a whole bunch of those reasons up his ass.
The only recent invention regarding lubrication that is worthwhile, is the locklube system. https://locknlube.com/products/locknlube-grease-coupler [locknlube.com] Lock that sucker onto the xerk, and you don't have to hold it. No leakage, you know that your grease is going inside the knuckle, bearing, or whatever it's supposed to lubricate. I love those things.

I'll meet your xerk and raise you a Zerk.
Thanks for the LocknLube link, if I was using my grease gun more often I'd buy one.

What is your point? Are you saying that body temperature has not changed, and the measurements are wrong?

Maybe you could read two sentences before you reply.
