> [abuse] why does it appear in the biographies of so many people who achieve greatness, often middle/upper-class? Because other people don't write autobiographies?

There are enough unconfirmed assumptions in this claim that the first open question is "are the author's assumptions justified?"

"Why do so few people in the United States exercise their right and privilege to vote?"

Turn it around: "Why are so many people in the United States denied their right to vote?" * prisoners and former criminals can't vote in many places - https://www.sentencingproject.org/issues/felony-disenfranchi... * (this just got a little better - Florida just passed an amendment that will give the vote back to 1.4mil former felons, which is a full 1/10 of the state's population and 1/5 of its African-American popu…

The apathy far outweighs the fraud.

> Why do humans, pets, and even lab animals of many species kept in controlled lab conditions on standardized diets appear to be increasingly obese over the 20th century? What could possibly explain all of them simultaneously becoming obese? Because diet is only part of the equation. The other major factor being exercise/physical activity (and probably some genetics). If you eat 'well' but sit at a desk all day, calo…

My pet theory (at least for humans) is that this is due to better dental care.

Care to elaborate?

I have yet to run into a clear reference to them before the 1980s and they may primarily postdate even that If you want to be aggressively inclusive you can go all the way back to the earliest recorded myths about talking animals.

Given that I’ve seen 1980s and before published books at used book sales where you yourself are put in the role of a cat (sometimes solving a mystery, sometimes not) I think the publishers knew there was a market out there

The question about Gracie jiu-jitsu is not so interesting anymore: In the early 90’s, there were simply very talented jiu jitsu practitioners who were close to the UFC. Now we’ve witnessed many strategies used successfully in MMA, like American college wrestling (Ben Askren, Matt Hughes), Thai clinches (TJ Dillashaw), kickboxing (Holly Holmes), and Judo (Ronda Rousey). In fact very few fights end with an interesting…

I feel that jiu jitsu makes UFC / MMA less interesting. I'm more interested in of the stand up combat sports like kickboxing. I reckon UFC is missing out by not having a pure standup division, without the wrestling/bjj. I know a former world champion kickboxer who says "Ground and pound? Where's the honor in that?". I thought about it a bit and realised he is right - where is the honor, sportsmanship in beating the h…

Why is there more honor in beating someone while standing?

The reason to include wrestling is that it makes the contest more closely approximate a real fight. In a real fight your opponent does have the option to go to the ground.

How likely is a real fight to be one-on-one, just you and the guy you're trying to kill?

> Does listening to music while working serve as a distraction, or motivation?

There was a study which determined that people do mundane, routine work equally well with music or without it, but if the work required creative thinking, music lost to no music. A possible conclusion is that music engages the regions of the brain which are required for creative thinking.

That's just one study, however, and I doubt that I would be able to find a link to it now.

Personally I find that if I turn on “Techno Live Sets”[1] when mashing the buttons, I'm risking doing all the work that's to be done, in one day. On the other hand, some neo-prog post-industrial breakbeat doom would regularly steal my attention. But I've already listened to months if not years of techno cumulatively, while I'm very much in the market for some post-industrial breakbeat doom.

Also, I have a distinct thing about voice in music: the clearer the words, the less suited the music is for the background. Mumbling to complex hip-hop rhythm ok, clear and loud declamation not ok.

Most notably, I can mostly turn off my attention to words in English, which is the second language for me, while my native language gets straight into my brain's speech recognition centers—I've been suffering from this quite a lot when around TV or pop music. Inane lyrics in my language immediately throw me into stupor of trying to find any sort of reason behind them, while I'm comfortable with any random drivel in English until I explicitly try to decipher it. I've also noticed that I can consume text in my native language pretty fast without any conscious effort, while I can't really skim text in English—I have to pay attention or I drift off. It seems like for the second-language English, parts of the brain that transform it into meaning have to be consciously engaged, while the native language gets the treatment on the subconscious low level.

Probably more likely than that it's a one on one fight where you both agree not to wrestle.

For some martial-arts, it may be necessary to account for the likelihood that bystanders will actually be close enough to be able to intervene before the fight has concluded.

By definition, an unrestricted one-on-one fight is more likely than a specific subset of one-on-one fights, since the first possibility includes the second.

But neither is likely at all.

Also unlikely: picking a fight with someone who weighs about the same amount you do.
