...my entire body is one large stoma or stomate.
I used to be able to breathe in through my nose and out through my mouth simultaneously, creating a constant stream of air. Learned from playing trumpet. You decompress your lungs and use the muscles in your throat to flex the nasal cavities like little pumps.

It's called circular breathing. Not surprised you've never heard of it, it's rarely used and the quality of the note is usually shit.
I always remember that breathe has an E at the end because you have to make an E sound in the middle.
