What Stands Out
What To Check
What it is
Nasal breathing, carbon dioxide tolerance and why how you breathe matters more than people assume.
Audiobook or print
Both links are below, and for some books on this shelf that choice genuinely matters. Narrative and memoir usually win on audio. Anything you will want to flip back through — frameworks, diagrams, protocols — is better in print, and I say so on the pages where that applies rather than pretending every book works both ways.
Who should skip it
The cons above are the honest version. If two or more of them describe you, this is not your book, and there are forty-four others on this shelf.
The Short Version
Worth it for the appendix and the nasal breathing case. Hold the fringier chapters loosely.
