laughs in natural 20/15 vision, but quickly devolves into an asthmatic coughing fit and starts looking for his inhaler
The reason for widespread short-sightedness is unknown but the best study I read showed that kids playing indoor sports have significantly worse vision compared to the same outdoor sports.
My theory is because we look up close frequently, our eyes become adjusted to it. As a very near sighted person I can tell you, I see much better very close (a few inches from my eyes) than someone with 20/20, like magnification. Try it. I also used a screen probably 8 hours a day even since early childhood (lol, 90s parents).
We are really well adapted for pre-history and there's evidence we were happier and healthier back then (murder/rape was common, though). "Sapiens" covers this fantastically in general.
Before the invention of books, short sightedness was far less common. So let's blame Gutenberg.
It's not fair!
And then I realize I would have most likely died during birth anyway..
I have several different ailments that would have killed me a hundred years ago.
Natural selection? It relates on your thoughts taking off other stuff at night.
Can we make this happen for all the science-denying idiots out there? Let's start with RFK.
Along similar lines, I think about this for any post apocalyptic scenario that disrupts supply lines. Even if things are okay in terms of food, I regularly take medication that one would presume would be hard to get without modern society. In that situation, if I broke or even scratched my glasses, it seems very unlikely I would find functional replacements. I'm not physically disabled, but I am very limited, so in any real conflict I would lose. Quickly.
In prehistory or any future environment like that, I wouldn't last long.
Infections were a big killer before antibiotics. We have vaccination these days because of the horrible things that used to happen without them. Just having clean warm water and soap readily available was a luxury back then.
And yet some missininformed people think vaccines are evil.
In most of prehistory (and still some parts of the world today), you'd have a tribe/society that would choose to help you and look after you.. Fuck, even herds of bovines do this to some extent.. It's kind of shit that we're letting the rich stop that from happening.
My, aren't you a big kitty!...
Absolutely, yes.
