Maybe, but from a practical standpoint, conditions treatable by epi pen are long term issues that people will bring up with a doctor.

Headaches don't involve doctor visits and it would be prohibitive to simple treatment to require one.

There's no perfect harm elimination, there is a balancing of factors.

>What does Adderall do from the perspective of the person taking it?

It makes tasks feel more rewarding.

>Do their thoughts stop racing?

Not directly, but rather than go back and forth between different trains of thought, it's easier to stick to a single one which is a lot less stressful.

>Do their thoughts still race, but they can be traced for longer?

I feel that racing thoughts are a product of not thinking them to their conclusion. Once concluded, they can be let go easier.

>Do they have the ability to lock onto, and stick with a particular thought rather than their focus drifting all the time?

Yes. It's easy to stay focused on something that feels rewarding and meaningful. Adderall lowers the bar for "rewarding enough" to stick with something.

>What happens when you take Adderall for a few months?

The effects diminish a bit, especially the euphoria which is common in the beginning, but it remains quite effective nonetheless.

head bobbing allows pigeons to momentarily fixate their gaze on various objects, giving the photoreceptors in their eyes enough time—about 20 milliseconds—to build a complete picture of the world around them.

And while it often appears as though the birds are moving their heads back and forth, there’s actually no backward movement at all. The bob is actually an illusion, scientists discovered in an experiment. The birds are simply moving their heads, allowing their vision to stabilize so their bodies can catch up, and then they’re on the move again.

This happens so quickly, it appears as though they’re using a constant bobbing motion.

Note that my dog is a complete anomaly. I did not feed him for the first 4 years of his life, because I didn't regard him as my dog yet and feeding as my chore, him being one small family dog among many (my mom's hobby).

Yet the mutt still loved me.

This never, ever happens with dogs. Ever ever ever, to make it especially clear to Redditors what I mean.

>If allergies, and especially anaphylaxis, are so common, why do we still need prescriptions for epi pens and such?

Prescriptions are used to limit dangerous chemicals/medications to the use of folk who 1. need them and 2. have been instructed on how to use them by a physician.

Whether or not they are commonly used or required doesn't factor into it.

A 6' human will have something like 2.5 psi more blood pressure at their feet when standing, compared with their head. That's not a lot of pressure, but their blood vessels still need to squeeze a little more when standing to have the same circulation as when laying down. A bat will have less than 0.2 psi of difference upright or laying down (or upside down vs laying down). That's probably not really significant enough to require additional adaptation.

Some people do, but certainly not all.
Ultimately people's love of animals generally comes down to Superficial factors, like animals being cute, interesting or just in general fascinating, to conscious factors like animals providing a sense of importance and purpose in (for example) pet owners, to subconscious factors like the lack of judgement and a casual relationship.

Criminals who are given the task of tending to animals (for example cows) can wind up caring immensely for the animal because it doesn't judge the criminal for his past mistakes or even flaws, and instead responds to immediate actions. negative behavior has a negative response, positive behavior has a positive response. the simplicity is endearing.

JPEG was developed by the Joint Photographic Experts Group and the CCITT, with the intention of being a free and open standard. Where they did use patented technology, they specifically negotiated with the patent holders to get free use rights.

Lossless JPEG, in particular, used a ton of patented technology, whereas lossy JPEG was pretty much patent-free. Some lawyers were concerned that the agreements may be CCITT/JPEG might not cover all patents, so lossless JPEG was immediately hamstrung by legal concerns, plus the fact that for most purposes, lossy JPEG was plenty good enough and gave much better compression.

There was a bit of a controversy, because in 2002, a company with a patent on the DCT technology behind lossy JPEG, suddenly started instructing lawyers to sue any company using JPEG files or using software which could handle JPEG files. This patent wasn't listed in the legal documents produced by JPEG/CCITT, so they didn't have a legal agreement in place. In the end, the company decided to drop the claims, because the patent wasn't actually valid.

GIF has also been problematic from a patent and legal perspective, although PNG has been designed from the ground up to be open and avoid patented technologies completely.
