Life tracking with bluetooth and sensor tech

This device manufacturer has decided to call the small tracking devices cookies:

Mother’s potential use is intriguing: Each Mother unit talks wirelessly to a set of smaller tracking devices, dubbed cookies, that can sense motion and temperature. You can put cookies on things and people – on your body to gather data about how much you walk, on your coffee machine to track many espressos you drink, on your front door to track whenever it is opened, on your toothbrush to see how often and how long you brush … and so forth.
