Haptic reminders and related technologies are described in which a wearable first article receives a rule. In some variants the rule was used in a second article and the delivery is programmatically conditioned upon one or more articles like the second article having worked well enough with the rule. The received rule occasionally triggers haptic energy via the first article to remind the wearer to eat more slowly, hydrate or exercise more often, or otherwise perform better. Such reminders may serve other purposes or be conditionally extended if a wearer does not improve. Other improved modes of discernment and notification are also presented.
