The word "Yankee" originates in calling early Dutch colonists Jan-Kees, Jan and Kees being common Dutch male names.

One theory is that Kees is a dialectal version of "kaas" (cheese), so Jan Kees is "John Cheese".

Which is what the name of Monty Python member John Cleese would be if his father hadn't decided to change it to "Cleese" because he didn't like being named "Cheese".

Harmonicas are amazing instruments. At first people assume them to be like toys (you can buy really cheap ones everywhere) and initially the concept seems really easy: 10 holes, drawing air produces some notes and blowing air produces other notes. But the more you get into it, the more amazing it gets. Soon you discover that you can bend notes by positioning your tongue in a specific way and your repertoire increases…

Fabulous addition. For anyone looking to see what a master harmonica player looks like, highly recommend looking up blues traveller / John Popper. In particular, there’s a live performance of no woman no cry that has John Popper alongside Ziggy Marley. Mind blowing. Watch it. You won’t regret it. https://youtu.be/9zk0HFG5mDw

Don't forget about this guy, at the ripe old age of 90:

Very few people know the potent facts about the brain: * your neurons are not in your "brain" 90% of your neurons are not in what you generally denote by brain. They are in your cerebellum. The cerebellum has a distinct neural architecture, that difference is in fact clearly visible with the najed eye. A very poor simplistification would be to call it our GPU. * the spinal cord is huge and is structurally a contiguou…

I don't know where you get the idea brain does not include cerebellum. This is completely false

Re-read my sentence, yes the cerebellum is part of the CNS and so is the spinal cord. Is the spinal cord part of the brain? Why not. What I meant is what people generally denote and imagine when we speak about the brain, is actually the cerebrum https://www.cancer.gov/publications/dictionaries/cancer-term... The cerebellum, pons, etc are distinct extensions.

I've described this on HN before; forgive me if you've already seen it. I have chronic migraine. It sounds worse than it is; I rarely suffer attacks anymore, and when I do, they're usually mostly harmless, as in the case I'll describe below. Contrary to popular belief, migraine is not a headache. It's something a little more like an epileptic seizure. Intense headaches are one common symptom, but there are a lot of o…

I used to suffer from these auras from 2005 to 2015. I never had one before, and they completely disappeared since then. I don't think they were ever followed by any headache, either.

A funny but related story: I was visiting Paray-le-Monial where there's a diorama about the visions of Saint Margaret-Mary ( https://en.wikipedia.org/wiki/Margaret_Mary_Alacoque ), who is at the origin of the current cult of the "Sacred heart of Jesus".

In fact from the descriptions, it's very clear that the brilliant, shimmering lights that she related as her visions and revelations of the "Sacred Heart" were simply scintillating scotoma from her migraine, then followed with terrible access of headaches that she interpreted as her mystical ordeal from God.

> your neurons are not in your "brain" 90% of your neurons are not in what you generally denote by brain. They are in your cerebellum. Excuse the dumb question, but what's in the brain then? Or are you meaning to say that the cerebellum has a much higher density of neurons than the brain?

Well clearly it means the "brain" (the cerebrum) contains less than the remaining 10% neurons https://www.cancer.gov/publications/dictionaries/cancer-term... Shared with the midbrain and spinal cord. Of course I am excluding PNS neurons

You haven't experienced a whole lifetime. Every moment up until the current [whatever the smallest unit of time really physically possible is] is just a memory of an experience. Subjectively from your perspective there's absolutely no difference between having actually experienced all that and merely having memories of having experienced all of it. You could materialize into existence for exactly one moment and belie…

Now that's an existential crisis right there. There's no way to determine if I've literally flashed into existence and am remembering this sentence, and am thinking of how to continue it, versus actually existing on the timescale of a human life. Urgh. Then again, does it matter? Probably not.

There's another way to look at it: you can think of yourself as having just come into existence this instant, having inherited all memories and evidence of any previous existence.

Now you are blessed with the incredible gift of spontaneously coming into existence, plus a vast treasure trove of inherited experience (both good and bad) that you can explore and try to understand, and of inherited skills and knowledge that you can put to use however you choose.

Is this not just because most rapists are men (and sexual assaulters more generally are men), and the only people they can rape in a prison environment are other men? Which is also why prisons are segregated by sex, to avoid women prisoners being sexually assaulted, raped and impregnated by deviant men. If prisons had no such sex segregation, it would overwhelmingly be the women being raped, not the men.

yes but it doesn’t change the fact. the men who are on the receiving side are just as much victims regardless if a member of the same sex or differnt is the perp

True but I think the point is more that when men want to rape, they'll rape anyone and anything they can. Women, men, children, animals. Their depravity knows no bounds.

It does make me wonder if penectomy and castration should be the standard punishment for rape, not just incarceration. Otherwise they're just being given access to a new set of potential victims.

I've also suffered from what I've understood to be ocular migraines, characterized by the intense ocular disruptions. I went to the ER when the first one hit, because I thought I was going blind.

> It was disappointed. I didn't want to stop reading. I was enjoying the book. So I decided to keep reading until the scotoma made it impossible to continue.

I do the same thing now. I had one come on recently when I was lifting weights. I just decided to power through it. It was perhaps the most intense aural disruption I've experienced but the typical after effects (which, in my case, tend to be very bad and render me useless for 2-4 hours following an "attack") were almost completely subdued. I recall that I felt like I had a slight hangover and was able to fully function after it passed.

The saying "blood is thicker than water" is from the Bible. The full quote is "the blood of the covenant is thicker than the water of the womb," which means the opposite of how "blood is thicker than water" is used.

Any idea where in the Bible it says that? I spent a couple minutes searching and found many sites saying the same thing you did, but nobody cited which verse. I searched a dozen or so translations of the bible and did not find it, either. Which makes me wonder even more, as there were just as many sites saying it originated in 12th century writings.

I looked and the saying does not appear to be from the Bible
