    In a medical diagnostic system, given a binary health profile where each bit represents a specific vital sign or risk factor status, develop a function that identifies and activates the leftmost inactive health indicator (represented by 0) in the profile. The activation of this missing indicator is crucial for completing the patient's risk assessment profile, where 1 represents an active/monitored indicator and 0 represents an unmonitored indicator.
