A system includes physiologic sensors and devices. The physiologic sensors sense human physiologic data and the system processes and transmits signals representing the physiologic data. The physiologic data represent at least one physiologic parameter, such as heart rate, respiration rate, blood pressure, body temperature, blood chemistry, other blood constituents, muscle contraction, movement, activity, speech, and brain waves. The system also determines that a device and an object are in proximity to each other, and secures physiologic data at times when the device and object are in proximity to each other, in order to correlate a person's physiologic state while in proximity with or while using the object.
