1. Eyewear, comprising:
a frame;
an optical member supported by the frame;
a temple coupled to the frame;
a sensor coupled to the temple and configured to sense facial muscle movement of a user and generate electrical signals indicative of the facial muscle movement, wherein the sensor comprises two electrodes configured to make contact with a single temple of the user when the eyewear is worn by the user; and
a processor configured to process the electrical signals and determine a facial expression of the user, wherein the processor is configured to take an electrocardiogram of the user via the two electrodes used to determine the facial expression.
