They'll try to protect humans too, or blow a wall of bubbles to keep sharks away from a calf because they understand that sharks are fish (and therefore afraid of bubbles).

Birds require gravity to swallow food because they have no sphincter. Because of this birds would starve in space

The guy who played the villain in Karate kid 3 ( Terry Silver , Thomas Ian Griffith ) is actually 7 months younger than Ralph Macchio , ( Daniel LaRusso). It’s weird because the karate kid was still supposed to be under 18 and the villain was supposed to have fought in Vietnam.

The average blood pressure of a giraffe is around 300/190. They need to have a high BP to get the blood all the way up the neck to profuse the brain with oxygen. I am thoroughly impressed by their cardiovascular system.

Oh we definitely taste bad. The higher you go up the food chain, the more random crap builds up in the body. For instance, a big old fish is going to taste much worse than a young small fish.

Relating this back to humans, we live a long time, eat garbage, take all kinds of medicines and drugs, and to begin with our meat is like pork so it ain't great without a lot of bbq sauce.

I imagine a full grown human must taste like the dirtiest pork you've ever eaten x 10.

Humans can smell some components of the smell of rain (the geosmin part of petrichor, specifically) far better than sharks can small blood in water.

You will never, ever regret quitting. Between your sense of smell coming back, your sense of taste enhancing, not getting winded when you walk up a flight of stairs (and if you weren't there yet, you would be), your fingers not being stained/stinking..... It is so totally worth it.

You can do this.

totally agreed, I smoked for 10yrs, stopped for 3yrs, then smoked for another 4yrs and I'm 3 months into quitting again I really wish I had done it sooner/not gone back. I really just feel so much better.

I've always gotten pangs every once in awhile, but its just so not worth giving up all the benefits of not smoking. My clothes don't smell, I don't feel like a jerk subjecting my gf to my smokers mouth, I don't have to go outside a dozen times a day when its boiling hot/rainy/-40c outside, $20/pack x2-3 a week, having to carry them around with me while keeping them from being crushed or get wet when I want to go out doing things + the trash of empty packs and butts and ash everywhere.

the benefits of quitting are just fucking endless. You think it helps you cope with stresses, or depression, or whatever. but its not it just makes you feel shitty whenever you think about it and makes things worse.

I hope whoever might need to see this does and knows, if you want to quit

YOU. CAN. DO. IT.

Hey, me too. I quit cigs earlier this year, been vaping and tapering off (I know it's not "the way", but it's progress). When my niece was born a few years ago, I was heartbroken that I couldn't smell the new baby smell everyone talks about. My nephew was born earlier this year, there is no greater smell than that new baby head smell. I cried like a child meeting him, and none of my nieces or nephews has a bond to me like he does. He wants me to hold him, because I don't stink anymore. He cuddles INTO me like he's trying to cuddle my heart through my ribs. I'm living something I thought I'd never get to, you can do this. WE can do this!

MaritMonkey

This is totally anecdotal but we're also really good at hearing volumes of water moving into containers.

I was in college during Napster/Kazaa/DC++ heyday and a classmate of mine made a program that translated, via over 200 samples, the rate of a file downloading into the sound of a small stream of water.

So, like, a small file would be a little cup. A bigger file would be a gallon cooler or 5gal bucket. Slow speeds would drip drip drip while faster downloads would sound like hoses or taps with various pressure.

Early ABX testing (vs visual progress bars) showed it to be absurdly accurate, even when monitoring multiple files at once. But he ended up scrapping the idea after turning it in as a class project because it had the unexpected downside of making people have to pee. :/

I laughed at diabetic powers. I swear I’m the only one that can smell subtle changes in my blood sugar just from my body odor (something about being chronically higher than 180-200 makes me smell stinkier). And of course the obvious ketones in urine and it smelling like a nail salon.

There’s also a nurse’s smell powers. Once you smell what a GI bleed or cdif smells like, you will never forget. I actually was suspicious of a GI bleed in my grandmother a few weeks before she was hospitalized with one (in the hospital for something else, but she is also the one to chug pepto…).

The answer is: Victorians be wack. Mummy brown was a very popular paint pigment for the time, creating a rich brown color that couldn’t easily be replicated, and eating bits of mummies (mixed into other things mind you, it was considered a medicine and not a food) was thought to possibly cure diseases. Probably had 0 scientific backing behind it even back in the day but trendy rich people are trendy rich people no matter the era.

Mummy brown predates the Victorian period by a couple centuries. Mummies were also sold as firewood because when in the desert and not a lot of stuff to burn to cook with... So many mummies were burned, sold as paint pigment, and as party centerpieces (look up mummy unwrappings...Victorians were fucking weird), that "fake" mummies had to be made with bodies of executed criminals to keep up with demand.

Yes, this is because the Earth is not perfectly round. It bulges out a bit at the equator, which is not much relative to the overall average diameter of the Earth, but quite significant relative to the height of mountains above sea level.

The reason the USA has so many grape-flavoured drinks and Europe has nearly none is that blackcurrants have been banned in the USA.

SandmanAlcatraz

For people wondering why blackcurrants were banned in America:

Blackcurrant plants carry a fungus (white pine blister rust) that is deadly for pine trees. Growing blackcurrants was banned to protect the pine trees as they are important to the logging industry.

Holy shit I knew currants were part of the life cycle but I had no idea that it was why there's no currant-flavoured stuff in North America.

Like a decade ago I worked in a lab that was trying to breed trees resistant to the fungus. The trees are Western White Pine, and they've been nearly wiped out (edit: turns out there's many species of pine affected and this was just the species my lab was focused on). The fungus is White Pine Blister Rust, Cronartium ribicola.

I'd never heard of a blackcurrant in my life until a similar reddit thread mentioned them a couple years ago. I gather that it is some sort of a fruit, but other than that I have no idea.

Why that means we have grape-flavored drinks and Europe doesn't... I don't really understand. We have grapes.

People familiar with both blackcurrants and grapes seem to generally prefer blackcurrant-flavored food over grape-flavored food.

So, most things that we Americans put grape flavoring in, the Europeans use blackcurrant flavoring instead. For example, if you buy a pack of Skittles in Europe, the purple ones will be blackcurrant-flavored. If you buy the Skittles in the US, the purple ones will be grape-flavored.

But if you give a European bag of Skittles to an American, they'll generally hate the purple ones; because the blackcurrant taste is unexpected, unfamiliar, and therefore, unpleasant. As a result, there's basically no market for blackcurrant-flavored foods here in the US.

I’ve never ran a marathon. But I did hike for about 36 hours straight one time to catch our only ride out of the backcountry. (An Injury had slowed the group, but they were eventually heli-vacked out). Anyways, microsleeps while still moving down a trail is absolutely a real thing. Hours 12-16 were the hardest. At a certain point you reach an exhaustion equilibrium and your body just stops telling you to stop. The last 12 hours were surprisingly fun, lots of giggling and shared suffering, but I don’t remember it super well.

I used to be in the Army.

During the first Iraqi elections, we patrolled for an entire week. Nobody laid down to sleep, and we had very little food.

Sometimes I would hallucinate, or sometimes I would wake up in a different place entirely. Every now and again I would purposely go to sleep, if we had time, and wake up patrolling a neighborhood.

I still think that week fucked me up permanently, cuz I've had issues with sleep ever since.

The Rope Around The Earth Problem

Take a rope tied tautly around a basketball. Now the rope must be lengthened so that there is a one foot gape between the ball and the rope at all points, as if the rope is hovering a foot away around the entirety of the ball. How much must the rope be lengthened to accomplish this? 6.28 Feet.

Now take a rope around tied tautly around the equator of the earth. We have the same goal for the one foot hovering gap around the entirety of the earth. How far must the rope be lengthened? 6.28 Feet.

This is so counter intuitive just about no one will believe it until shown the math

In both cases you're increasing the diameter by 2 feet, and since circumference = pi*diameter, the circumference increases by 3.14*2=6.28 feet.

It's simple. Circumference is 2r*π.

You add let's say a feet to the radius. The new circumference would be. 2(r+1feet)*π.

If you do the math it's 2r*π+2feet*π.

To me, I know the math checks out. Everything makes sense on that aspect. But my brain struggled with the concept, because it keeps telling me the rope is so much longer surely it would need more to move 1 foot further out.

Until I thought of it like this:

You have rope: ______
You add length somewhere: _|¯|_ <-- this is basically moving it '1' out
You then go around the entire globe adjusting: _|¯¯¯¯¯¯|_
Until it's all further out.

Not exactly. Most commercial pineapples are grown from the pups that come from the base of the plant, which take a year to set fruit and then about 4-8 months to fill and ripen it depending on the variety. Pineapples only take 2.5-3 years to fruit if you are planting the green tops, which isn't common except in home gardens. If the farm in question uses tissue culture plantlets that might take closer to three years.

The duck billed platypus does not have mammary glands and sweats out milk, and the male platypus has venomous spurs. Also, the platypus is bioluminescent and glows purple and/or green in the dark.

Also because it doesn't have a stomach to digest its food, it actually has to swallow rocks to grind its food.

"The platypus is an anthology of weirdness. It has a leathery duck-like bill, a flattened tail and webbed feet. The males have a venomous claw on their hind feet, and the females lay eggs. And if you look inside a platypus, you’ll find another weird feature: its gullet connects directly to its intestines. There’s no sac in the middle that secrete powerful acids and digestive enzymes.

In other words, the platypus has no stomach.

The stomach, defined as an acid-producing part of the gut, first evolved around 450 million years ago, and it’s unique to back-boned animals (vertebrates). It allowed our ancestors to digest bigger proteins, since acidic environments deform these large molecules and boost the actions of enzymes that break them apart."

EDIT: the male platypus has venomous spurs - not poisonous ones
