The Health Map for Physical Activity (Human)
A Health Map is the navigation layer above the Topics. It shows the full path, the cross-area benefits, common mistakes, the contexts in which it applies, where experts disagree at the area level, and what is changing now.
One example — free preview
How much does a fitness test say about your lifespan?
Mainstream: Higher VO2max goes with longer life in large studies.
Contested: Another view: the link is relatively weak and partly reflects reverse causation.
What survives: Track it to see change; do not read it as a forecast.
The full Roadmap applies this pattern across every area-level tension. Path, Mistakes, Context, and What's changing now follow the same approach.
