Stirrups originated on the steppe quite late - 4th-5th century CE and spread both east and west. Before that, cavalry was still effective - as the Persians, Hannibal, Alexander and others showed. You could, with training, use spears and swords without falling off. The Sassanid Persians developed heavy cavalry, with high-cantled saddles, extensive armour and lances, before stirrups.

In most cases, allowing a business to flounder and die is fine. In the case that the business is producing something that your population would die without (food) allowing the business to flounder and die is maybe not a good idea. The hilarious amount of corn produced in the USA means that the entire rest of the world's agriculture could fail or be made unavailable and the US would still have a good supply. This protects against disaster, war, and other geopolitical events.

Obviously there are negative consequences to subsidizing corn (and other foods) to this degree, but I think it's important to temper any assessments with the fact that the subsidies are meant to prevent mass starvation should things go terribly wrong in the world.

There's also a huge problem with the less regulated throttle bikes used by delivery drivers. E bikes are very popular in Europe but it's largely the pedal assist variety used by normal people.

Source?

>You can have great sleep, diet, and exercise habits and still develop major depression which increases your inflammatory markers.

I agree

>Lesser forms of depression can get better with or even treated with working out and better sleep but not major depression.

In your post you keep on referring to different forms of depression.

Major depressive disorders is just the name for basic normal depression. All the other types are worse or specialist types of depression.

>platelet-to-lymphocyte ratio is one of the biomarkers for inflammation. Exercise, sleep, and diet don't affect that ratio. Only major depression does. Your assumptions are wrong here.

Seems like exercise does acutely effect the ratio.

>Compared to NLR, far less evidence is available on the PLR in the context of exercise. Of the five studies investigating the impact of acute exercise on the PLR, three showed increased values post-exercise, indicating an inflammatory response

>It doesn't mention the type of depression and it only REDUCES not completely treats major depression.

Again major depression is the normal basic depression everyone is talking about. If it was some other type they would specify.

The current view is nothing "cures" depression. So pretty much every study will just talk about treating it.

These medications and lifestyle changes are treatments for diabetes.

Sure people can use meds. It's like when I cut myself, I might take a painkiller. While it isn't fixing the underlying issue, it does help.

>The fact that you would post stuff that doesn't prove your point and yet be too illiterate to understand what you are reading is wild

You are the one who thinks that "major" depression is like some super duper serious form of depression, rather than just the medical name for basic clinical depression.

You are the one who doesn't know that every study on depression treatment will just talk about treating it rather than curing it.

It is easy to hit a high number of proteins on a vegan diet. I can hit the daily requirements of a bodybuilder in terms of protein without protein supplements or other drastic methods. A lot of lentils even have a higher or the same protein content per 100 grams than meat.

Meat is the more expensive protein source. Legumes are far and away healthier and cheaper than meat, not to mention cheaper to produce and requiring a smaller land area to grow.
