According to one aspect of the present disclosure, an apparatus for taking pictures or videos triggered by pre-selected changes in a user's biorhythms includes a wearable camera for taking one or more picture and/or videos. The wearable camera is configured to be worn by the user. The apparatus also includes at least one processor configured to receive a biorhythm signal indicative of at least one detected biorhythm of a user. The processor is configured to compare the received biorhythm signal to a biorhythm threshold and, in response to the received biorhythm signal exceeding the biorhythm threshold, to simultaneously trigger the wearable camera to take one or more pictures or videos.
