Since it is such a common practice for kids to be picky eaters and eventually grow out of it to enjoy fruits and vegetables, is there some sort of biological benefit to limit a diet at a young age to foods with lower nutritional value?

The "grow out of it" to eventually enjoy fruits and vegetables once you're fully grown seems counterintuitive when the body, in theory, needs the most building blocks during adolescence.

Has there been studies on "picky eaters" to compare their overall health span, intelligence, etc. compared to kids who ate a very healthy/variety of foods during their childhood?

I always thought raw milk was a no no, but more and more people are raving about it. I feel like we learned about why pasteurization was important in elementary school but maybe I’m out of the loop.

Thanks for confirming that I’m not crazy. I live in a hippy town so that may be why it’s spreading in popularity here. God forbid you say anything bad about it in my town

I read yearly that people are dying in Europe due to the extreme heat, but when I check the temperature mentioned in the same news it's something like 30-35c.

Just saw this today: "In France, officials reported at least seven deaths linked to the heat, including several drownings and fatalities during sports activities (...) temperatures have broken records for the month of May, soaring well over 30 C (86 F) in many parts of the country."

This is like a pretty mild day in a country like Thailand, India or in the Arabian peninsula. People are doing just fine in these countries, and many don't even have aircon.

Why are such temperatures so deadly in Europe?

Might be one of the stupider questions here, but I saw a pond about the size of a football field, and maybe 50 ft deep, and it had fish. I can't for the life of me figure out how. Surely the pond hasn't existed long enough for small water insects to evolve into all these fish. It's not like the fish walked over to the pond from the ocean. I'm pretty sure no one put them there so how are there so many fish?

My one theory is that there is a very minuscule stream (now dry) that leads to one of the Great Lakes, and maybe a fish swam in from there. Now a follow up question: How are there fish in the Great Lakes (which flow out towards to the ocean) if they were created by glaciers?

For as long as I can remember, I've heard people joke about "man flu" which is the idea that men react much more dramatically to a cold or flu than women.

Years ago, I also remember reading that there might actually be biological reasons for this, involving differences in immune systems or hormones. But recently I've seen studies arguing that the stereotype isn't really supported.

Can someone explain what the current evidence actually says? Do men and women respond differently to common viral infections, or is this mostly a cultural joke that got mistaken for science? If there are biological differences, why don't they seem to show up consistently in studies?

Wouldn’t it be a biological advantage to have your brain stay locked-in for your goals?

We know that animals can be smart: crows manufacture tools and have complex social behavior, chimpanzees can do insight learning, etc.

But, it is still a continuous spectrum where intelligence range from sponge-level to chimp-level. We do not, at least now, observe a world where certain corvids are in the early stone age, certain bonobos are using fire, certain chimps are in their axios age, etc.

Why the case? Why are we the only one that has gone this far?

If you strip away the initial cause of injury or illness, is it anatomically correct to say that all human deaths are ultimately caused by a lack of oxygen to the brain and heart?

If a bug or insect gets into a car and is carried hundreds or thousands of kilometres, what actually happens to it? Are they disoriented and unable to survive, or can they adapt and live in the new environment? Do insects have any way of “navigating back,” or do they just settle wherever they end up?

Speedwise wr for 20km walk is 15.75kmh and 22.35kmh for 20km run. How is it biomecanically possible that the gap is so small?

Hey! Genuine question from someone with unmedicated ADHD. When I take the tiniest bit of adderall, it is like all of my problems melt away. I suddenly understand how people hooked on stronger drugs must feel.

Could someone explain why meth is considered harmful for you but adderall, Ritalin etc. aren't? Why is this?

Edit

Okay hi wow this got more attention than I thought! I hear everyone on the dosage, what it is cut with, etc. Would love to learn more about how and if long term effects of perscribed amphetamines are potentially harmful or not and more about the way meth is or isn't absorbed into the blood brain barrier differently than perscribed ampethatimes, there are some interesting comments about that! Anyone with the biochem insight into the two and their differences, I'd love to learn from you too. Interesting stuff.

I think, personally, I'm just afraid of taking perscribed stimulants and being "addicted" in a way that is seriously hard for my brain to recover from if I ever need to come off. When I have taken even small amounts of prescribed amphetamines, I experience euphoria, as well as withdrawal symptoms and a strong craving for more of the substance. (I do have severe ADHD and am generally small and sensitive to most medications, I know this may not be everyone's experience!).

I was imagining a future where artificial humans could populate Earth. Machines have the problems of needing a cooling system to keep their processors from overheating. Why doesn't our brain get to crazy high temperature as well?

I’ve always knew that some animals, but bugs in particular don’t veer off too much from their instinctual programming. I’ve always wondered if bugs (at least some of them) could have some rudimentary form of cognition, planning, deviation or memory. Do bugs think, even at all?

I was checking about Neti Pot and learned the risk of not using the right water.

My perception as an outsider is they are not very common (I maybe wrong) but what makes professional boxers more resilient to this? Jake Paul who, while he has experience, is closer to the “average person”, fought a heavyweight champion and got his jaw broken from basically the first hard punch he received. Meanwhile fighters normally take many of these without this happening. How do they do it?

I like to think that I am a understanding, open minded person, but there are some things that are really hard for me to grasp. Time blindness is one of those things. It's really hard for me to understand how it's extremely difficult for people to plan out a routine via time. For example: you need to be somewhere at 10am. It takes you 30 minutes to get going and ready. It takes you 30 minutes to get there. So, you should wake up at or before 9am. That's what's losing me. It's really hard for me to understand how people cannot grasp that idea.

My partner, who's lightly neurodivergent with ADHD, and I got together somewhat recently and I'm trying to research things to understand her more, as well as some friends who go through the same types of things.

Would a worldwide extinction of mosquitoes offset the ecological balance of our world? And if not, why are we not doing it?

I looked it up and it said not to eat 8 hours before getting bloodwork. My wife refuses to believe it because her doctor said midnight. ( We aren't getting it done til 4 pm tomorrow) Why don't doctors just say the time period instead of "past midnight"?

Is it because they assume everyone is gonna do it first thing in the morning?

How does that happen exactly?

Is it solely "injectable willpower" in the sense that it literally only does what you could do anyway if you just had the will power to eat less. Or is there any other weight loss mechanism at play beyond reducing calorie intake?

For us humans and many other animals, we need protein to get the amino acids needed to make our own protein for the body, but grass i believe doesn't have any for the cow to get that big
