A semiconductor-transistor-based system and device that are designed to, but are not limited to: electronically outputting electronic-semiconductor-transistor-voltage-level-based-state-machine-assisted-user-menu-selection display associated with electronic-semiconductor-transistor-voltage-level-based-state-machine-assisted collection of user-physiological information, associated with electronic-semiconductor-transistor-voltage-level-based-state-machine-assisted collection of user-conduct information, and associated with electronic-semiconductor-transistor-voltage-level-based-state-machine-assisted obtaining of food-based information. In addition to the foregoing, other method aspects are described in the claims, drawings, and text forming a part of the present disclosure.
