       | Today it requires wearing a mask to effectively capture the data.
       | I wonder if we will see this done acoustically or via some other
       | non-intrusive, remote method.

         | Would be interesting if this could be used to reliably diagnose
         | sinus issues.

       | 
       | Because you can't require a warrant for biometrics that you
       | impart to the (public) environment around you, like fingerprints
       | on a door handle, saliva on a discarded cigarette, or in this
       | case... air.

       | Kind of a silly personal anecdote, but growing up, my father had
       | a unique "strained" nostril breathing pattern and bad sleep apnea
       | + COPD. I became 'hyper aware' of people's breathing patterns -
       | to the point where people at work had fun with it - standing
       | behind me breathing normally. I could identify who it was > 90%
       | of the time (they were not trying to breathe quietly or
       | differently). I often thought of people's breathing signature as
       | sort of factor to identify them by. I certainly didn't think I
       | was the first person to note this.
       | 
       | More interestingly, I'm also able to pick out people who have
       | early signs of "decreased health" based on their breathing
       | pattern at rest - I don't think it's overly difficult.
       | 
       | This study appears to cover both aspects - creating a breathing
       | fingerprint and estimating BMI. I certainly wasn't aware of
       | breathing differences associated with cognitive state. Bravo to
       | the researchers for formalizing all of this - hope some positive
       | interventional techniques are driven by these findings.

           | Your thoughtful question is definitely along the lines where
           | the research could change health outcomes. Apple Health
           | currently tracks trends over time and can alert if any
           | disconcerting trends are identified. If Apple were able to
           | capture a breathing signature at rest, say once a month,
           | trends could be identified (via training data, as you
           | mention) and data optionally provided to healthcare
           | providers.
           | 
           | Some people who are alone (including my father) have no idea
           | that they have sleep apnea or 'odd' breathing - for apnea,
           | they're obviously asleep, and for other breathing factors,
           | it's usually a slow and unnoticeable progression.
