Right, like uhh you know the average life span for a healthy male used to be 25 years right? Did you think that was for no reason? Smfh.

Did you think 90 years passed and suddenly the life span tripled?

The idiocy

Edit: to make sure some of the responses aren’t misunderstanding my point - medicine.

Scientific advances. Technology, research, people knowing how to literally wash their fucking hands added years to the lifespan.

And yes it has tripled in some cases. 18th century France the life expectancy was twenty four years old.

This increase to what we see today is LARGELY due to medical care and sanitation alone.

It’s all over the board back then, in fact, because of sanitation. Diseases would.come and go and life expentencies would sink like a tanker because sanitation was non existent.

So yes I exaggerated the time span, obviously, but I wasn’t kidding about the tripling part - if a bit vaguely.

25 was a shortened life span due to agriculture. We live longer than cave men now, but it hasn’t tripled.

No? Medical care and sanitation. Unless youre speaking of a specific event in time. But yes it has tripled in the 25yo cases? Avg life span now is in the 70s.

I’m speaking of natural humans, not humans during the 18th century. And I’m counting children.

Nearly doubling is still very good! In case this needs to be said, I’m on team science, not team antivax.

I think everybody else was inferring a healthy 25 year old man, not life expectancy from birth (counting children).

Or their idea of “natural” is 18th century France.

It was an average largely brought down by childhood mortality. If you made it to ten you’d probably see thirty, if you made it to 25 you’d probably see 50ish.

This (at least I think) exactly. There were so many deaths at birth/during childhood from things that are easily fixed now. I’ve also seen some places say if you made it to the teens, you’re pretty likely to hit 50ish.

25, that is quite a historical extreme, isn’t it?

In the wild, average live span was around 40 to 50 years. There’s even studies about the evolutional reasons why we live longer than other primates/why we are the only hominide with grandparents.

Sure, it is an extreme. As in my edit I stated: this is due to sanitation. It is all over the board throughout the 15th-18th century world because pandemics/diseases/epidemics came and went and sanitation was so low and medicine was so bad that people dropped like flies, and thus did the life expentency average.

In particular, my “25 year l.e.” example was about 18th century France.

Those make sense to me, but I’ll be honest with you, where I struggle is with the idea of sunscreen. How did our ancestors live outside constantly without any sunscreen but if I’m outside for more than 2 hours in the summer without it I come home looking like a burnt lobster?

I’m sure the answer is that I’m ignorant, or the “natural causes” of yesteryear were really just undiagnosed skin cancer or something, but I have to admit it does seem like a real negative adaptation here from the viewpoint of my uneducated mind.

We need sunscreen becuase we’re indoors 8 and months of the year, then run out naked to sunbathe.

If we were outside more and naturally built up a tan it really wouldn’t be that much of an issue for most people.

I mean I definitely see your point, but as I understand it even field workers are encouraged to use sunscreen and farmers and others who spend a lot of time outdoors are at greater risk of long-term damage, not lesser, despite this supposed acclimation.

It’s all relative. Sunscreen itself has carcinogens. It’s kind of like blood pressure medication. It’s easy and works. But obviously exercising and eating better would be better.

Same with the sun. Gradual exposure and not baking deliberately in the sun would be better, but sunscreen is easier.

At the end of the day we’re extremely well adapted to the sun for the most part, within reason.

Back in the day it was normal to die of skin cancer at 30. These days, we prefer to avoid it.

Well there is that protective layer in the atmosphere that we fucked up.

The ozone layer is slowly healing itself, but we still have a long way to go before it is stable again.

Also as others pointed out, we don’t work the fields and spend most of our time outside any more…so the natural protection isn’t building up like it did in the past.

You have to remember that people generally wore long sleeve clothing and hats. They did not expose much skin to the sun historically

If they lived in areas with a lot of sunshine, they developed dark skin. If they didn’t, they developed light skin. Beyond that, if they were light skinned and moved to areas with a lot of sunshine they wore long sleeves and wide brimmed hats even in hot weather, and their face and neck skin turned to leather. They typically didn’t live long enough for skin cancer to be a concern.

As I said in a other comment, I think “they didn’t live long enough” is a bit of misconception. I’ll repeat my comment here rather than writing it out again:

"So I’m no expert, so take this with a grain of salt, but it’s my understanding that while average ages were much lower in the past, this number is heavily skewed by infant mortalities and deaths due to preventable disease. As I understand it, the expected age of an otherwise healthy individual was pretty comparable to us today. More people died young, but those who didn’t lived about as long as us. So I don’t think not living long enough for skin cancer to take effect really jives with my understanding of history.

But again, I’m not an expert and the likelihood that I’m just an idiot who is wildly misunderstanding things is, frankly, high."

It’s the “more people died young” part that meant it wasn’t an ever present problem like it is today. We might have had more ozone to protect people too, although that’s just wild conjecture.

That’s a great question! We didn’t really need sunscreen in prehistoric time because we adapted to the environments that we lived in and we didn’t migrate to new environments as quickly as we could in later times. Those adaptations are getting more tan more easily and growing thicker skin. We can still see this now in people who don’t use sunscreen and their skin looks tougher and more leathery. Also, there were some ancient sunscreens ranging from simple mud to pastes made from ground plants.

Human skin stood up better to the sun before there were sunscreens and parasols – an anthropologist explains why - The Conversation
