It seems your school really sucked, and not just with regards to learning as most schools seem to do. For many people, though, school is also a source of lifelong friendships, romance, and other good things.
I’m sure my experience with school is not unique. School was a prison, quite literally a mandatory daycare service which as a side project may have taught some kids. But really, I’m 30 now. I look back in awe that we subject our kids to this. The friendships you forge would happen without being in prison.

#72It doesn't really surprise me much that lactase persistence should be so strongly selected for in a relatively short period of time. Cows and other ungulates possess a rather magical ability to turn something that can't be digested by humans (cellulose) into something that can (milk). Opening up the huge caloric and nutrient resource of cellulose to humans in a relatively replenishable way had to be a giant benefit t…

Milk production is also a continuum of data samples over the life of the animal. Eating the animal is one data sample and you can’t duplicate the animal after collecting the data. Selecting for milk production would be a lot more accurate than selecting for meat tastiness, longevity or even, to an lesser extent, health.

Lactase persistence isn't the only (or even first) way to convert inedible flora into food. For one, you can simply eat the cows, the way it was done for most of human history. If you absolutely insist on dairy though, the genes for lactase persistence post-date dairying by a few millennia and many people who rely primarily on dairy today still lack the genes, like most Mongolians. They've adapted different productio…

You could also harvest and consume the blood[1], without having to kill any cattle. 1. https://www.atlasobscura.com/foods/cow-blood-kenya-maasai

Milk is nutritious though. Besides calories it also provides amino acids. For non first world communities it thus formed an essential part of a healthy diet.
That's not the point in contestation. Specifically it's "how obsessed we are with giving milk to kids because it’s so healthy" The word "because" is a fascinating bridge. Whatever follows after reveals unstated assumptions hidden deep in the speakers mind. I'm objecting to the specific premise that it's some rational decision made individually by each parent based upon nutrition. Instead I'm claiming our cultural hab…

mongolians are also atypically short for a population with a tradition of dairying, though — those with lactase persistence are among the tallest in the world thanks to the massive caloric surplus reducing environmental selection against height in times of scarcity

that's an interesting theory ive never heard before. Is it generally accepted that Northern Europeans are taller because their society is less prone to famine?
However it also worth noting that if we go back farther than the past century or so, it was non-european populations that were among the tallest in the world. That would be populations like the Sioux, Athabascans, and Maori. This kind of points to how big a factor social, economic and political context has on population metrics like height. Moreover, certain diets and populations simply make for shorter people. Disentangling all the effects is complicated.
For the data, I'm half-remembering a table from a paper I read years ago. Ourworldindata has a very similar table with pretty reasonable citations, so it checks out:
