How often have you touched your face today? It's a habit hard to shake but one of the big health advised to stop the spread of COVID-19.
This smart wristband vibrates whenever you are touching your face to remind you not to do it. It can be programmed to different areas in the face (a bit similar to face id / touch id programming). I wonder though if you are supposed to have two of these and if this will build a Pavlovian reflex over time. I wouldn't want to have that.
