Protocols
A guide explains how something works. A protocol says what to do about it. Each one names a problem, the state you would rather be in, and the way between the two.
What a protocol is
A problem you can recognise in yourself, an objective in one sentence, the handful of things that actually move it, and what to watch so you know whether it is working. Nothing in one that is not traceable to a source, and an honest line about what we do not know.
There are two so far. That is not a soft launch, it is the honest state of it: writing one properly takes longer than writing about a subject, because it has to be right about a person rather than about a field.
One-sided dominance
How one dominant side starts a chain that runs all the way up into your neck, how to work out which link comes first in you, and what to do about it.

Rounded shoulders
Why your shoulders roll forward, why stretching your chest provably does nothing about it, and what the research says actually works.

Looking for the subject instead
If the question is how something works rather than what to do about it, the library is the other half of this.
