How you breathe is like a fingerprint that can identify you

Also, make sure to use a different CSPRNG for your gait randomizer, to avoid entropy starvation.
Epiglottigeal toggling is an esophageal inefficiency.
A tongue twister for the age!
And you won’t attract the worm
The correctly identified .968x42=40.696 of the participants.
Also any standard-ish physical activity that comes with instructions usually includes breathing in those instructions. So I would expect results to vary substantially depending on where they found the study participants.
I rarely get to confirm whether I'm right or wrong, but everyone sounds slightly different.
I only do it for my own amusement. I don't inflict my "guessing" upon my colleagues, no one knows. For me, it's a lesson in working out "how may I maximise my anonymity".
I generally respect the "polite silence" rule upon entering the ceramic room - someone else must break the rule before I will.
Don't read on if it literally will cause more anxiety.
I was in a different 'cubicle' and noticed that the shadows meant I could see that the person next to me was using their phone, so now that's an additional consideration for minimising my identifiable footprint on the throne.
“Mark? Is that you?”
“…Tim?”
“Yeah, any update on the report?”
“…”
“OK, no problem buddy”
Still, I can see it. My wife and I are probably equally fit, but she breathes much faster than I do. I also notice that I sometimes don't take a breath (or feel any need to) for several seconds, if I'm being sedentary.
Normal adult breathing rate is 12-20 per minute. So by the pigeonhole principle, if you don't pause breathing for several seconds when idle, then you're breathing too fast than what's considered normal. Your wife is hyperventilating, which could be a sign of stress, or a compensatory reaction to metabolic acidosis.
Your body needs less O2 when sleeping and your respiratory rate slows as a result of that and many factors.
I highly doubt someone sleeping next to you is materially taking away from the O2 you're breathing in. If so, you'd be fairly out of breath in a room full of people during the day.
Unless the room you're sleeping in already has such low level of O2, you might need to look into a monitor or even using a fan to move some air.
A CO2 monitor might be helpful too?
Looking at the real-time stream the breathing was noticeable, at 2Hz it would probably be very useful, if you have the dedication to write the tools to analyze the data.
I was thinking about doing this with a fanny pack where I put the sensor and battery pack in the fanny pack and a strong magnet at the opposite side of the strip in order to measure my breathing frequency during excercising.
Driving home from work, I get at least 2-3 "shocks" when other drivers cause close calls. I flinch, get a surge of adrenaline, and have to breathe to calm down. My sine wave is disturbed. Let's say a driver swerved close to my vehicle and I flinch and swerve away.
The next day, a driver drifts close and I instinctively get a shock, flinch, and swerve away. I didn't intend to be jumpy and nervous, but apparently my electrical system is still "echoing" from the day before.
At work, I experience anxiety, and it's a "softer" shock, but the long term result is nervousness, twitching, holding my breath in anticipation (of an attack that never comes), feelings of dread.
People talk about fixing upset emotional states and psychology, but in thinking about this, I characterize my own problems as needing my electrical system tuned-up.
How often did a farmer 1000 years ago get adrenaline dumps from fast-twitch motor neurons as he zoomed 80mph down the highway? And yet now it's literally all day. Vehicle noise at 4am, jump awake. Phone rings, jump and flinch. Driving, etc.
I don't think we look often enough at the physiology of stress from the perspective of the electrical signals generated by the nervous system. It seems like all kinds of problems come from it. To the article's point, I know my breathing has been affected from stress and tensions. I don't think i'm particularly unhealthy, so I think a lot of people could relate to feeling "not-unhealthy" but also really twitchy and disturbed from stress and tension.
In my thinking about this, fitness and health come from creating the electrical impulses in a steady, predictable way (i.e. walking, lifting) such that the electrical pathway can remember it's baseline frequency and "strengthen" the good frequency. And hopefully smooth-out the peaks and valleys of the signal interruptions caused by stresses.
This is a hypothesis.
It might be true that electrical signals and magnetic frequencies define something fundamental about our physical reality, but don't underestimate utilitarian power of imagination and metaphor.
Think about trees, feel better.
Yeah, it turns out if you can strap a device to somebody then wow you can identify them.
This is interesting, but not a big surprise!
Now if they can do this from an external passive sensor like a camera or microphone, then yeah that would be a neat result.

Cynically, you could use it for surveillance, similar to how they do face recognition or temperature scanning in airports.
The flip side of the coin is that it could be used for better authentication or medical purposes. Maybe your oxygen tank could realize you're breathing different than usual to warn you that you might be having a seizure, stroke, or heart attack. Or maybe we'd have "breathe to sign in" similar to FaceID
This is me trying to use our fucking touchscreen stove
Landlord's kitchen, I didn't know this was even an option until moving in here or I'd have asked some questions about wet hands. I'd not have thought to ask about cold hands, like when I held a freezer product for a minute, though
I'd think it a mere annoyance if there was a physical OFF button. There is not. You can go to the cellar and trip the breaker I guess? Otherwise, you better have reasonably warm and dry fingers (it can deal with a bit of moisture and chill, but has limits similar to trying to use a phone in the rain)
Gotta say it looks sleek though, when it's free of fingerprints and other usage marks
I love technology
Whoever designed that thing should be fed feet first into a wood chipper.
We don't normally have fruit laying around but maybe I can find something conductive and finger sized and keep that around. Good idea!
It'll be a small challenge though: the stove checks that you decisively press it with an object of the right size: changing size or position, like when pressing down slowly or shifting accidentally, doesn't work; and random metal objects, spilled liquids, or light touches can't change your settings either. It also needs to stay put for a second before anything happens (not annoying at all) or 3 seconds for the on/off button. I gotta give it some credit here for the efforts they took to make this a usable and safe product. It just can't work when there's any liquid anywhere near the button you're wanting, including the off button, you have to dry it first
Here's a fun fact, the CPAP machine lowers my Heart Rate Variability. HRV spikes when I sleep part of the night without it.
Hate to break it to you, but you're in for an upsetting aging process.
Also, your breath already isn't silent. Your brain attenuates the expected sounds, and our ears aren't nearly as sensitive as some microphones, especially microphone arrays.
See if you can notice where in your body feel that impulse.
This is meditation.
If breathing can really be used to detect health or mental states in the future, that sounds promising. But it also makes me a bit uneasy. If even our breath can be tracked, is that one more doorway to being monitored?
