Don't touch your face stop lights.

I don't know about the rest of the world but I am finding out how many times I touch my face in a day. Time for some retaining of that habit. I decided a good way to retrain myself was to have a stop light on my hands for a few days or so. I have been accused of being MacGyver at times, which can come in handy. So I made stop lights for my fingers. All you need is a couple LEDS (Mine came from dead furnace control boards) and 3 volt button batteries and some old rings. I hot glued it to a copper ring for now, may get green fingers unless I keep gloves on.
