Depends on where the age cutoff is. Some of those have a greatly reduced life expectancy. At 40 years of age the heterocygotic people have more symptoms compared to the dead ones.

Don't trust the AIs further than you can throw them.

Their digestive enzymes only dissolve dead cells and bacteria. Whatever live tissue is left within the wound finally gets a chance to grow. Surgically cleaning a wound always damages healthy tissue too, the wound is bigger than it was before. Hopefully it's also clean afterwards so it can heal, but maggots are more precise at it.

In the article: Shocked how well it works.

Not because it's such an odd thing to do.

It's not super common, but the maggots are so much more delicate when cleaning a wound than surgical options. They don't damage what healthy tissue remains so it can grow and close the wound faster. And some of those wounds are so horrifying the maggots look downright cute in comparison.

Most organs consist of more than one cell type. Fatty tissue is white to yellow. Muscle cells are red meat, looks the same in all mammals. As the heart is a muscle too, it's mostly red, with a bit of fat around it, and some shimmering white to almost silver connective tissue. Fasciae in general are really pretty. The single fiber is white, but in smooth organized sheets they can shimmer like pearl in pale rainbow colors.

White blood cells are translucent, only the red blood cells are actually red, platelets are yellow. White blood cells climb around in almost all tissues, so even a red muscle has some of those, and yellow-ish nerve fibers and the red-grey-white of blood vessels, it's a mix.

When you put any cell under a microscope most of them are translucent and barely visible. There are a bunch of organelles inside, filled with whatever this cell's product/purpose is. That's where the color comes from. Like chloroplasts in plant cells, just those are green, the rest is translucent. Few cells are so colorful that it's noticeable when you look at just one. The sheer mass of them makes organs as colorful as they are.

To really tell things apart the cells are dyed. There are different dyes/stains that attach to different parts of a cell. They even come in fluorescent. Some are as simple as binding to anything acidic or basic, others cling to just one specific molecule. Without dye it's hard to impossible to tell what is what.

Modern agriculture is problematic, though. There's "peak oil" when oil production starts dwindling because it's getting harder and harder to extract more of it, but there's also "peak phosphorus". Me extract the stuff to make artificial fertilizers and it's not an indefinite resource.

Soil is being washed and blown away. Extreme weather events are becoming more and more common making it all the more vital to have healthy, spongy soil that can handle massive downpours and store water. We can't go on with open-soil farming, putting the same four crops everywhere conditions be damned and trying to make up for the problems with artificial means.

It's not being romantic, or glorifying the "good old times" (which they weren't). Nature has a little bit of practice in how to handle fluctuations. Using the same concepts to make food production resilient and regenerative isn't tree-hugger woo, it's efficient.

Ruminants and grass land go together. We killed most of the wild ones, leaves using livestock to fill that ecological function. Whether that's cattle, sheep or goats, or on much smaller plots, maybe just some rabbits depends on the area and what the land and people need.

People want to preserve old breeds of livestock (it's a resilience thing too, variety is good), but you can't keep every individual until it drops dead on its own. A healthy population needs natural predation, or selection by humans. How do we keep old, not-currently-economically-interesting sheep breeds alive? We eat them. Draft horse breeds mostly survived the switch to combustion engines by also being damn tasty.

Mass production of meat in feedlots is a terrible idea. But animals are part of healthy ecosystems. Manure is a fine fertilizer. It's perfectly possible to design productive local farming systems that regenerate soil, improve biodiversity, bring good plant crops AND produce animal protein.

Put the animals back where they belong. Switch back to cows that can live on grass and don't need soy or other protein-rich feed to keep up their insane milk production. Chicken kept on a small scale, to eat scraps and weed food gardens are a benefit to the system, not a problem.

Meat wouldn't be dirt cheap (and shouldn't be), and there'd be less of it. But not keeping animals would be wasting an opportunity. They can turn stuff that we can't eat into something we can while producing fertilizer and doing chores around the farm.

Teeth say more about that than bones. Bone matter gets swapped out constantly and will show more signals about what the recent diet was than historic (unless it was bad enough to cause permanent bone deformations)

Enamel hypoplasia is commonly used as an indicator of "stress" during development in archeology and anthropology. It's not perfect by far, but when several children have the same sequence of defects as their teeth developed it's more of a sign of general illness or malnutrition than a single physical trauma to that tooth.
