• track TV usage

      • simple timer which tracks on vs. off

      • no other measurement. TV is treated as by definition unproductive and cognition-sucking time

    • track how long the kettle spends boiling water

      • start is defined as "turned on from off"

      • done is defined as whistling

      • finished is defined as the action of turning off from on

      • how do you sense how much water gets poured in

      • doesn't really solve a problem other than measuring what something (boiling water) happens in parallel to something else
