The dactyl keyboard family with built in trackballs are way nicer than ones with built in track pads at least from my experience. My personal favorite so far has been a Charybdis from bastardkeyboards. Expensive but I don't need a mouse anymore for being productive.
The buffalo bike is one that was specifically made for developing nations and the project prioritizes local assembly and repair, while the bike is designed to sacrifice weight and aerodynamics, instead offering heavier-duty parts like thicker rims, puncture-proof tires, high-capacity racks, etc. This bike has two chains to reduce the likelihood of a critical failure and an internal coaster brake hub which is more robust to the elements.
Your average low-cost bike isn't intended to be used in environments with rough terrain and high contaminant concentrations without regular maintenance, and especially older bikes with things like cup and cone bearings which are more susceptible to dirt getting in, thinner tires which puncture more easily, and nonstandard bits and pieces like derailleur hangers which predate the UDH standard.
The immune response to diseases has to be developed over time, not to mention the fact that the introduction of those drugs drastically accelerated the evolution of the bacteria, viruses, etc. I can't speculate as to the health of hunter gatherer civilizations but modern diets and until recently the prevalence of antibacterial soaps and products in homes have definitely changed immune systems. Just look at covid, where in just a period of a few years the amount of infections due to other common diseases like influenza or strep have shot up due to kids not being exposed to germs during the lockdowns.
The problem arises when there's outside pressure to use the tools, or now you're maintaining code written by someone else through the use of the tools, where it could have been good enough for them because they don't have to deal with downstream effects. At least that's been my negative experience with AI coding assistance. You could say "just get a new job" but unfortunately that's hard.
The last libertarian post I saw wasn't getting downvoted and it was by a guy who wanted to set up meetings with cartels to improve the efficiency of their drug dealing business.
The causes of obesity in the US are well known and reported on, just not as "health" pieces. Food deserts, car-centric infrastructure, poor work-life balance, rising costs of groceries, low access to preventative screens. The only novel research in my opinion would deal with micro plastics and the effect they have on hormones.
A number of YouTubers have made the claim that their views were affected but not revenue, so it seems like the monetization is based on ad-watching views at least.
Elden Ring is a great example of a game where the difficulty is largely self-imposed, if you play using all the tools the devs give you like summons, magic, certain weapons, etc the game becomes almost trivialized. Not saying that's a bad thing necessarily, in fact the opposite, I think FromSoft's "difficulty slider" replacement is one of the best ways of going about it, however I think the difficulty overall is overstated by the "real souls players" who hamper themselves so as to experience all of the mechanics.
