## Summary

Google Research introduces an investigational framework that builds a coachable health age metric from wearable data such as resting heart rate, steps, sleep, and Active Zone Minutes. Its SensorWM world model simulates 12-week what-if habit trajectories, which a language model turns into coaching plans. In a blinded study, lifestyle coaches preferred the counterfactual-grounded plans in 71.4% of evaluations, and the authors note the models are research prototypes, not clinical diagnostic tools.

## Why it matters

The framework turns passive wearable data into a health age metric and simulated coaching plans, with clinicians and coaches rating the plans, useful for judging whether wearable coaching can move beyond tracking.
