The paper benchmarks a new biological drift framework against Reference Change Values (RCVs) for 62 routine biomarkers, showing severe drifts often exceed RCV thresholds, suggesting meaningful deviations from individual optima.

This study examines how acute stress affects the balance between model-based and model-free reinforcement learning in pathological gamblers and healthy controls, finding stress impacts this balance more in controls than gamblers.
