What's an interesting fact you learned recently?
-
Recently had lens replacement surgery (AMA?) which gave me 20/15 far sight vision. Seeing things up close is difficult (need reading glasses) but making out details from far away objects is unreal. It's like having HD vision.
Anywho, 20/20 simply means that you can make out details at 20 feet that the average person can make out at 20 feet. In my case, I can make out details at 20 feet that most people can only make out at 15 feet.
If you have 20/40 vision, it means that what most people can make out at 40 ft, you can only make it out of it were 20 feet away.
Now you know how that works.
What was the recovery from that surgery like? Any pain / discomfort / concerns?
I am considering getting lens replacement for my dog if I can come up with the money, but financial concerns aside, my other biggest concern is how stressful / painful / risky that kind of procedure might be for her.

They're also older than Polaris. Not just older than since Polaris has been our North Star, but older than the star itself.
God damn the ocean is terrifying.

I'll probably butcher this fact, but 20/20 vision does not mean you have perfect vision. It means you have average / normal vision.
I've always had 20/20 (or perhaps better) vision. But now that I'm on the downhill side of ancient, I'm noticing that my vision is blurry. Especially while watching TV, reading, etc.
Yet, at both my primary care provider and at the optometrist, I'm able to accurately see all the letters on the vision charts and based on that I have 20/20 vision.
The optometrist (or maybe it was an assistant) explained that it's pretty common and that 20/20 is just average vision. It doesn't mean your vision isn't blurry and it doesn't mean you won't benefit from glasses.
The more you know!
I learned this the hard way earlier this year when I got lasik. I used to be able to read the clock from across the room in my house with my contacts, but now that I have 20/20 without contacts, I can no longer make it out. So I guess the contacts were giving me a slightly higher than average vision.

Yeah, my glasses actually correct past 20/20, but my contacts only correct to 20/20. So everything is more blurry when I wear my contacts.

Well, not being a dog, I can't really say for certain, but I'm sure your puppy will be fine. For me, there was little to no pain at all, even during recovery. Only mild discomfort, and I mean very mild. It's outpatient surgery and the actual procedure only takes a few minutes (for one eye). It was really no big deal at all

Not a new one, but I've learned more recently:
Water does not last forever, is not all dinosaur pee. Natural processes create and destroy it, nonstop, since forever.
Got any plants nearby? Those fuckers are busily cracking water into glucose and oxygen so that you can breathe and eat. Have you said thank you once?!
6CO2 + 6H2O + light energy → C6H12O6 + 6O2
Take a shot of baking soda for your heartburn, oh boy will you create water!
NaHCO3 + 2HCl → NaCl + H2O + CO2
CAVEAT: The gas comes up your pipes, the water goes down your pipes. Violently. Probably a gravity thing. Not for the faint of heart, but hey, no heartburn!
the water goes down your pipes. Violently.
That's what salt water does. That's how people die when they are in a life-raft and drink seawater: defecating terminally.
So I hear, thankfully only second-hand.

You can graft a tomato plant and a potato plant together so the one plant can produce potatoes underground and tomatoes above ground because they are from the same family.
i hear you can do that to some fruit trees too.
like oranges and lemons iirc?

wow. Do they grow that fast or is there some mechanism that one triggers with the plant?
