Princeton is developing an electronic ‘tooth tattoo‘ for detecting bacteria. My money says development plans look something like this:

• Version 1.5 sends a text to your phone telling you when to buy Altoids,
• Version 1.8 will tell you how quickly you need to buy Altoids, and
• Version 2.0 incorporates social media analysis and performs a risk analysis of likelihood of getting a date, thus potentially saving you a trip and having to get off of the couch. (Which in turn informs the Energy Conservation Module which sends you a free iTunes download and updates your thermostat.)
