Also, although the article is mostly true, there are some inaccuracies:
>> Neurons and cardiac muscle cells don't reproduce after childhood
There is some evidence showing a slow cell turnover in cardiac muscle, estimated around ~1% per year in young adults, falling toward ~0.5% in older people. Most neurons don't regenerate, but there an evidence that some parts of the adult brain (such as hippocampus) still produce new neurons, although the number is very low.
Liver regeneration is not perfect either: https://www.youtube.com/watch?v=rOv7Sr3X-eo .
Complications with healing are pretty brutal. Necrosis, amputation, infection are all common without the built-in cascade we have.
That's why so many professional athletes take MSM (Methylsulfonylmethane). Their bodies would not be able to recover as quickly without the extra sulfur.
Some people also have rare diseases where they don’t have clotting factors so require a transfusion of clotting factors before surgery for optimal wound healing.
Megakaryocytes are primarily bone marrow cells.
To the author: thank you, you made my day. It had been a very, very long time since I last read an article on the Internet that felt written by a human being - with humor, some poetry, and science.
Almost like Apple with component serialisation.
Immune attack of the pancreas is usually a disease of youth. Type 2 diabetes which is overwhelmingly the diabetes associated with aging is not an autoimmune disease.
When we noticed the signs and went into the ER a few of the (younger) doctors thought it was Type 2, while the attending knew it was just late onset Type 1.
The Greeks chose liver because it symbolized the defiance Prometheus had against gods.
For example in Persian poetry the word liver is found pretty much everywhere you would expect to see the word heart.
"You are my liver" is a nice/romantic thing to say to this day.
It could have been because the liver was regenerative and they were using the titan with the regenerating liver as another reference to humanity, or it could have been as someone pointed out because predators like to eat the liver first, or it could have been that you can take damage to the liver and live for hours afterwards in agony whereas the same amount of damage to the heart or lungs is apt to cause death to come much quicker.
Perhaps there are undiscovered variants out there were the eagle or a serpent or some other animal attacks his genitals, or his eyes.
But at any rate the Eagle ate his liver, it means nothing in particular, and at the same time it means every particular interpretation we can place on it.
Just went and checked, evidently he never said anything about it.
old American translation of Galen and Hippocrates for anyone interested, as it can be difficult to find otherwise

So by destroying Prometheus' liver, Zeus attempted to destroy his human emotions, including his pride and defiance against gods.
Possibly because it's filled with strong acid.

I watched a Ted talk where the speaker suggested our large brains with their high energy consumption would not have been possible were it not for cooking.
(If we are talking about hunter gatherers, not poor exploited peasants)
We are certainly much healthier, with the little trinkets we keep in our houses.
If you made it past age 5 as a hunter-gatherer you’d likely live to 50-60 years of age.
