I am in awe about how wonderfully engineered by evolution the body is. E.g., what we are able to do with it and how it heals itself when we have an injury. Sure, many people would not live long without external intervention, but many others would. I still want to see the robot that can survive 80 active years without maintenance.
chistev•1h ago
The human body can't survive 80 active years without maintainance. They take drugs, they see the doctor, etc.
CookieCrisp•56m ago
What did people do 500 years ago?
EduardoBautista•55m ago
Die as a child at alarming rates
lukan•49m ago
But those who did not, got quite old without ever seeing a doctor.

(If we are talking about hunter gatherers, not poor exploited peasants)

If you made it past age 5 as a hunter-gatherer you’d likely live to 50-60 years of age.

Interesting. Yet as someone approaching the first of those two last numbers, I would say that that isn't very old at all
steve_adams_86•9m ago
Humans have assisted each other medically, supported injured and disabled tribe members, and sought out medicinal herbs since long before history was written. I'm not sure how you'd delineate between modern health care and when humans never had some notion of health care and/or support when bodies enter failure modes. We don't survive well without a lot of assistance and care, and living long lives required plenty of bodily maintenance regardless of how fortunate and healthy we were.
markyc•1h ago
no you don't
arcanemachiner•57m ago
Well, so much for that discussion.
dgunay•55m ago
Well, we do at least have to eat enough food and sleep ~1/3rd of our lives. That's kinda maintenance

ericmay•45m ago
When you watch those sci-fi shows and folks have nanobots implanted in them that heal wounds really fast or do other cool things I can't help but think in many ways we already have that technology we just need it to do more, faster as our brains and ability to create things have outpaced the rate of evolutionary change.

Other animals do get heart cancer, which is fascinating. It's still very uncommon compared to other cancers, but not virtually absent as it is in people.
bbor•1h ago

   I greatly resent having to be a biological organism and subject to all the poor engineering and design decisions that entails.
The first word of that sentence implies its absurdity quite beautifully. She resents, therefor she is.

And then this:

  Brains. After you reach adulthood, neurons don’t divide. If some of your neurons die—which happens every day—then they’re gone. If you get a brain injury, the other neurons will try to “learn around” the injury, but the neurons themselves are never replaced.
We need more neuroscience in schools! This summary is technically correct ofc, but to imply that the brain is missing some obviously-better option is absurd. We're meat that thinks, y'all; it's far from crap.
someonebaggy•43m ago
IIRC the slow loss of neurons is more than balanced by the additional fine-tuning - unless you get dementia, if course.

Loss of neurons isn't disastrous as long as it's not too many. Babies are born with several times more neurons than children have, and spend a few months letting all the useless ones die. Apparently it's better to start with a random tangle and prune it to shape (like cutting a box hedge) than to make a hedge grow in a box shape to begin with.

And IIRC brains can grow more neurons under some circumstances (certain drugs?) - they just normally don't.

rzzzt•28m ago
"While questions remain regarding the precise extent, rate, and functional relevance of adult neurogenesis in the human brain, as well as important methodological considerations, multiple independent approaches now converge in support of its persistence throughout adulthood."

> Evolution decided the good outweighed the bad, and I expect that evolution was right.

We can expect evolution to do the right thing for the genes. Not for us.

cortesoft•1h ago
I get its just a framework to understand what is happening, but I always hate the phrasing of describing a 'decision' to a process like evolution. There are no decisions being made in the process, just a series of outcomes that lead in a direction
CookieCrisp•53m ago
Indeed, I’ve heard so many people misunderstand it because of this type of wording. Like there is still some plan and series of steps we’re following - which really misses the whole point and why it’s worth knowing in the first place
someonebaggy•45m ago
Evolution is literally just the observation that there are lots of things that self-replicate.

That's it. That's the entire thing. Plus some nuance about things that self-replicate faster than other things...

It occurs at all levels. Amyloid protein in Alzheimer's patients is self-replicating. So are cells. So are individual parts of cells. Sometimes things replicate by being parts of a larger thing that replicates, sometimes they don't. It's all one big chaotic tangled mess with no particular purpose or design. Human cells evolve, so do humans, so do human societies. So do rocks.

Rocko can't have kids, because Rocko is just a stupid rock.
vconnor•41m ago
The punishment for Prometheus stealing fire from the Gods and gifting it to humanity, was to be chained to a rock and having an eagle feed on his liver which would regrow the next day.
bheadmaster•22m ago
For what it's worth, Prometheus was a Titan, and Titan was immortal, so his liver regrowing the next day wasn't really that special. If eagle fed on his heart, or lungs, they would've regrown too.

The Greeks chose liver because it symbolized the defiance Prometheus had against gods.

seizethecheese•22m ago
Why would liver signal defiance?
Bluestein•14m ago
Humors perhaps. Not my area, so I do not recall the correspondence ...
Sleaker•10m ago
It was the believed area of emotion, passion and 'soul'. I think western/modern religion has morphed from the liver to the heart essentially.
jephs•9m ago
There are a bunch of Japanese words (including a several loanwords from Chinese) that use the liver / gallbladder metaphorically for courage. Both derive from associations between the humours and personality / behavior. I have no idea, however, why both Eastern and Western naive psychology associate gall with, well, gall.

Anybody on HN knows platforms to discuss this ?
gchamonlive•34m ago
This is a platform and we are discussing this, which means such a platform isn't enough for what you need. Not judging, actually I've felt a degradation in engagement quality as of late, maybe it's personal bias, but the discussions seem more shallow or aggressive.

In any case, what would you expect from such a platform? That would help with recomendations.

Aeolun•29m ago
I feel like this is obvious. Eventually dying of all the weird body failures doesn’t inhibit your ability to procreate, but if you cannot survive alcohol or other various poisons you’ll never make it to a fertile age.

Picking the wrong berry from a bush isn't so difficult. Ask me how I know. And, for my second encounter, don't think because you see an animal eating it, it's safe!

Because alcoholism forces hunter gatherer cultures into settlements, which are the next stage of civilization and reward those doing that choice?

Why is it absurd to say that the human brain could be better? That seems obviously true to me.
dekhn•16m ago
the claim isn't complete, either. Recent research has demonstrated adult neurogenesis (growth of new cells that originate from neural stem cells).
card_zero•3m ago
Oh, fair point, I did the pathetic fallacy. Beneficial thing, then.
bheadmaster•8m ago
I phrased it awkwardly. Simply put, in Ancient Greece, liver was something like heart in modern society. It was the seat of human emotions.

So by destroying Prometheus' liver, Zeus attempted to destroy his human emotions, including his pride and defiance against gods.

bell-cot•14m ago
I'm thinking the Greeks chose liver because it is the first thing that many predators will eat from a kill - large, more nutrient-dense than almost any other tissue, and relatively quick to access.
bryanrasmussen•7m ago
There's really no knowing why the Greeks chose liver, or some specific Greek chose liver.

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.
