Resources
The practical layer of Health Captain: habit guides you can start today, the questions worth taking to an appointment, the numbers to call in an emergency, and the organisations we cite so you can read the original yourself.
Six resource areas
Start with the one that fits the moment
Some of these are for a calm evening and a cup of tea. One of them is for the worst ten minutes of your year — that one is worth reading before you need it.
Health Guides

The short explainers we are producing, organised by topic, each tied to the guide it summarises.
