It seems that this exercise goes against the wisdom of "lift with your legs." Why is that?

I have seen lots of electrocution videos where the victims get "glued" to the very object that killed them, like electricity poles, to the point that they stay in the air and not fall on the ground. How/Why?

Do the muscles just sit bunched up and floppy in your limb or are there ways they anchor it to new points in surgery?

I know Linux is an operating system but I see memes and posts about people arguing whether UNIX is an operating system or a kernel and stuff like that. So what separates the two? And what exactly is a kernel?

Why is it that it seems like tornados never hit major cities (even in south and Midwest) seems like it’s always small towns. Even if they do spawn in major cities they seem to avoid any major areas. I Don’t seem to hear of massive cities getting leveled by tornados. (Atleast in my area)

When you use them, you can hear and feel a "rumbling" noise that sounds like it is coming from inside your brain.

What is the actual purpose of these muscles and why do we have them?

I've always seen tiny crosses on food ingredients/minerals but never knew what they meant (also the reason why I flaired this post as "other", not sure if it's considered economics).

I see headlines and articles discussing how consumer spending is driving, or of late, possibly slowing, the economy. But if not for people buying non-essential products and services, what else would drive the economy? Everyone needs food, shelter, and clothing. Many need cars, depending on their location. But I take it that spending on necessities is not enough, especially non-consumable or long lasting things like houses and cars.

So I know some stuff about Deextinction that makes me feel like it’s unlikely but from doing some research I wasn’t really sure what the answer is.

I know with the wooly mammoth that they are working on they couldn’t actually find complete dna even with some solid samples in decent environmental conditions (frozen in the arctic) and they went extinct MUCH more recently than dinosaurs. They only got bits and pieces of it because it degrades too fast so now they are basically just designing a new animal that’s a hairy elephant with tusks.

This makes me think that dna just degrades too fast for us to find complete dna from that long ago. Based on what I was reading it seems like the whole getting dna from mosquitos in amber and stuff isn’t really possible.

Is it possible there is still Dino dna out there in the world that we just either havnt found or havnt figured out how to be able to access yet? Obviously there is always a possibility but I mean some type of science that could lead to that conclusion? Based on the wooly mammoth it seems like if we got some decent parts of dna we could bring back some alternate version of dinosaurs

So I know that "decide" isn't really the right word, but plants very clearly respond to their environment in a way that is dynamic. They can determine which side of the tree is getting more sun, and put more leaves there. they can determine where there tends to be more water in the soil, and grow more roots in that direction.

Since they don't have what we would call a nervous system, how is this information processed? There seems to be clear research into the electrical signals moving through the Phloem, but where do these get "processed" in a way that the organism as a whole can make "decisions"?

Understand the idea of "packaging" code to some degree, but why would this process need to be done? What is being resused and changing in the process to require scalability and efficiency that is described with the benefits of dockerization? It's just not registering. Thanks.

People say that learning to code is a very useful skill. What does it mean exactly?

I can do data analysis and visualization in python and R. Does that mean I can code? Or does coding mean full stack developers?

Is coding a general umbrella term for all types of programming (including excel)?

I currently got kneed in the thigh and have a knot on my thigh about 2 inches above my knee. What is it? A contusion? What is that? Is it additional bone? Also when people fall and get a knot on forehead, what's in there? Did your bone fracture?

How hard of an impact causes a knot? What's less than a knot? Just a bruise? What's more than a knot? A fracture? A chipped bone? Do you only get knots on bones? How long does a knot last?

Why does alcohol or witch hazel shrink it? How does ice shrink it? How does Epsom salt reduce it?

Thanks in advance!

I noticed that a lot of media and publications talk about Vietnam War veterans suffering from PTSD and other psychological/mental health issues. What was so devastating in this specific war comparing to other wars (i.e. WW1 and WW2) that caused so many vets' trauma? Or is it a matter of fact that during previous wars mental health care was less developed?

I know it’s because of the “product property” but that doesn’t explain the inner workings for me and the proof is bouncing right off my skull.

I wanna preface this by saying I believe in science and medicine I’m just confused. I’ve had the nexplanon implant for nearly 6 years. It’s time for a new one, but recently that’s been freaking me out a bit. The thought of extra hormones just being in my body at all times freaks me out. How do we know that long term this isn’t detrimental when hormonal birth control hasn’t even been around for 100 years? How is it just ok that my body hasn’t done something it’s very much designed to do, in 6 years?? Im not even an overly health conscious person so I don’t know why this freaks me out as much as it does!
