What I mean is: some boolean flags are perfect for the real world phenomenon they are representing e.g. is_light_on makes you understand perfectly that when it is true the light is on and when it is false the light is off.

There are other cases in which if you didn't write the code and you don't read any additional documentation, everything is not clear just by looking at the variable name e.g. is_person_standing, when true it's clear what that means but when false, is the person sitting? Lying? Kneeling?

I'm obviously not talking about cases in which there are more states, boolean would of course not be a good solution in those cases. I'm talking about programs in which there are only two states but it's not obvious, without external knowledge, which ones they are.

Would I receive notifications for new comments on posts I saved?

This is something I always wondered because some people have a bunch of theories about whether your head should face north or south or whatever, because of the earth magnetic field. Is there any science in this or just "superstition"?

Also, would it be better to have the head towards a window or away from a window, even if closed (e.g. in winter)?

I'm basically asking whether there exist "recommendations" on how to structure a bedroom backed by science.

After reading the abstract of the paper mentioned here I started wondering, why did human groups migrate away from southerner (warmer) places towards the north which is far colder and has less possibilities to grow crops and wild animals to hunt?

Was the population density too high?

And after they migrated, what did they mostly survive on? Were they hunters-gatherers? Did they cultivate? Was it not more difficult to survive in colder climates?

And if so, how much? Less, same or more than if it was actually charging something?

I'm in the EU if that changes something.

Wouldn't grow something from the inside require a very strong force to "move" the already present one? Instead growing from the last "layer" towards the outside would require a lot less force, but perhaps a lot more matter.

Is it even correct that trees grow concentrically?

Now that I think about it, how do plants grow in general? Hahaha

Update: for everyone wondering, yes, my question doesn't make sense because the i.e. contradicts the question. I don't want to correct it because I don't know which part to correct since I was wrong, I thought trees grew new parts inside and pushed older parts outside. So I could correct the i.e. and swap "innemost" with "outermost" but that would mean that people would read a question stating something that is wrong, or I could correct the question and swap "inside" with "outside" but I was wrong and I'm glad I learnt something today. We can all agree that I asked a weird question in a weird way, thank you all for your answers.

I mean, why evolution selected dinosaurs to become that huge?
