Yes! You have one on the tip of each finger. Just don't go too crazy because while they're rechargeable, they recharge very slowly.

what do you do when you're all out?

There's an emergency backup source located at the ends of your two other large extremities.

Makes no sense - I'd expect the opposite, given how easier it is to breathe in and out larger volume of air through the mouth than through the nose.

Why? Internally to the face the nasal cavity is massive and largely not restricted, especially compared to the throat (pharynx) which is restricted and can accept only small volumes of air at a time. Because of that the body must work substantially harder to permit large air volumes through mouth breathing. Just search google images for "pharynx". The visual difference in size is striking.

1. Your nose connects to the same tube as your mouth. Both paths pass through the throat and pharynx.

2. Compare the aperture size of the nostrils to the mouth and throat

3. Just look at the internal structure of the nasal cavity. It's a sensory organ and designed to maximize surface area contacting the air. In other words, it's full of obstructions that intentionally reduce airflow

Your thesis here is nonsense. You can't change a downstream restriction by changing conditions upstream.

If anything, adding restriction is probably what helps. By restricting airflow upstream of the lungs, you create a partial vacuum within the lungs which probably substantially alters the conditions for gas exchange. A partial vacuum probably greatly enhances CO2 rejection from the blood, but I'm not a biochemist.

first thing that came to mind is toothpicks. wonder if that's where the idea for the study came from. There was a time when men always had a toothpick in their mouth. Guess there was something to it! Seems like the simplest way to "try" this technique as it's certainly tested - or are their health risks for chewing on a toothpick?

Don't swallow it. Your digestive system can't really break down wood. Small particles will pass through, but you definitely do not want a punctured intestine.

I used to buy a pack of cashew nuts every day during lunchtime. One day I realized my jaw has started making a clicking sound and the muscle feels kinda loose. That was ten years ago; it's gotten somewhat better and I also learned to avoid that particular motion but never recovered.

I don't understand, what did the cashews do? They're pretty soft, no?

It's the constant chewing that did me in.

Huh, really? I didn't realise that was a thing, that sucks...

How about chewing gum? Especially chewing Xylitol chewing gum. https://www.webmd.com/vitamins/ai/ingredientmono-996/xylitol

In Turkiye, they have unflavored gum. I couldn't believe it!

Now I know, now I know. Interesting new fact of the day.

I wonder how it affects the teeth? Perhaps it helps strengthen them. Perhaps it wears them down more quickly. I couldn't hazard a guess.

[ETA: After reading about the TMJ elsehere, it looks like that mandibular joint is of greater concern. Gotta be careful with that wear-and-tear.]

I take it you invented some baseless conjecture. As a casual suggestion try searching the web for "mouth versus nose breathing" and see what the results say.

One of my biggest complaints about software developers is that so many claim to be engineers, but instead of measuring things (which is what engineers do) so many invent their own conclusions that tend to be wrong almost every time. It's disappointing.

I kept a platter pack of almonds by my desk. I had to stop because it was starting to make me feel ill. There's no poison risk AFAIK from store bought almonds which are the sweet (not bitter) variety.

Roasted almonds are more tolerable than raw. Raw walnuts are great too. Baru nuts can also be added to the mix.
