He has that look of, "Hey you're still alive. Time to fix that".

The kid in the yellow striped shirt creeps me out.

Without access to large livestock the inhabitants of Lake Texcoco needed a source of fertilizer. The only available option at scale was night soil (human dung). This led to a contender for the worst job in history, dung collector. Dung was collected at designated sites (public toilets) and transported via canoe to either farms or at large dumping (pun not intended) sites to be purchased at market.

Some topics would be chinampas, their use of obsidian for tool making, the evolution of the teosinte plant into multiple maize varietals, farm forests, dung canoes, maguey plant cultivation, lake ecosystem for food (from axolotls to lake skum tortillas), dual canal aqueducts, three sisters agriculture, and the methods of distribution via marketplace & the royal state.

As far as YouTubers I enjoy Ancient Americas and Aztlan Historian.

I suggest "Handbook to Life in the Aztec World" Manuel Aguilar-Moreno. It has a couple of outdated facts and has some misconceptions of how some of the religion worked (Ometeotl is a mistranslation and ongoing point of contention). Other than that it's a good textbook for getting a solid foundation of understanding on the subject.

The way that Mesoamerica built their civilization in isolation from the old world is intensely fascinating (example: making farm land in the middle of lakes). The uniqueness in the way they extracted resources to what was considered valuable gives insight into the way humanity develops. The Mexica Empire/Valley of Mexico Triple Alliance/The Tenochca Empire/Aztec Empire is particularly interesting due it's success being derived from an abundance of practices already in place rather than innovation (they revved up everything to an 11). Their approach to warfare emphasizing one on one combat was dramatic. Finally their methods of human sacrifice are some of the most metal things I've ever heard to the point where I find violence in fiction to be banal by comparison.

Good lord, I wonder if the character is public domain now?

I guess that's the other side of the coin. I'm a Mesoamerican history nerd and a lot of the articles on Wiki are sparse at best on the subject or outright misinformation (repeated misinformation I see almost verbatim copied and pasted). I see your point though, without an easy way of archiving information a lot of subjects would and have fallen through the cracks in humanity's notice.

Out of all the dudes that are nearly a 100 I think I would like to hang out with Everett the most.

Depends on the subject matter. The less popular subject matters still should be read in books.

I'm damn near 40, can I please talk to you about the Aztec Empire for an hour and a half?

Campaign editor and a level cap of 20. I just want to run D&D for friends in game.

I hate this timeline.

I hope the nightmare fuel is enough to get Megaman built before 2040.

So the "Aztec" (Mixtec Pueblo culture) had two major calendars The Tonalpohualli (count of days or days count) and The Xiuhpohualli ( year count or fire count). The Tonalpohualli is a spiritual calendar used for ceremonies and augury, it consists of 20 signs each given a thirteen day week. I've heard it speculated that it has something to do with the observable time that a human takes to gestate during pregnancy, but that's pure theory. The Xiuhpohualli is a 360 day count calendar with five extra days added to the end of the year (which were considered very unlucky). It was divided into 18 months that ran through the 20 day signs that the Spanish called a Veintena. This was used for feasts, holidays, and the planning of agriculture or war during the two major seasons (wet season and dry season). The two calendars would align every 52 years that culminated into a huge celebration called Toxhiuhmolpilia (New Fire Ceremony).

The birds (and technically one butterfly) refer to the actual numeric days one through thirteen in each given day (count the red dots). Not to go too much into details, but the birds were anthropomorphized into character traits that were associated with a person depending on which day they were born. The cultural context is pretty esoteric, but an example would be a person born on 13 would be wise because Toznene (parrot) looked bald. I have also read that the birds would act as a psychopomp on the occasion of one's personal death (apparently having corresponding red dots as their day) to fly off and deliver the part of the soul that leaves the mortal realm to a designated after life determined by circumstances of one's death.

Bolts of cotton too. Or maybe some jade or obsidian.

It's part of one of the more complete codices. It's post-conquest but anything from around that time that survived is precious.

Oh this is my jam. So in Nahuatl the beginning of the Trecena is Ce Ollin which is one movement/quake which ends in Mahtlactli Omei Atl thirteen water. Teteoh are assigned to Ihiyotl ( with a day bird to present) and Teyollia soul designations for management. These designations are assigned through the holy 260 day calendar year via patterns in the calendar. I love this stuff.
