Haptic reminders and related technologies are described in which a wearable first article receives a rule as a duplicate instance of a prior rule used in a second article programmatically conditioned upon one or more articles like the second article having worked well. The received rule occasionally triggers haptic energy via the first article to remind the wearer to eat or drink better. In some variants such reminders may be conditionally extended if the wearer does not adjust. Other improved modes of discernment and notification are also presented.
