How result tiers are assigned

The bottom score bands are designed to reflect clusters of habits that combine into a harsher outlook, especially around smoking, safety, and overall consistency.

The middle of the scale often represents users who are not catastrophically risky, but are clearly leaving years on the table through stress, inertia, or uneven habits.

A top-tier result does not mean immortality. It means the overall pattern of answers is cleaner, safer, and more resilient than the median result.
