Our minds have been on food this weekend, but it won't be much longer before "mindful" food will be in our stomach, heart, and precious bodily fluids. Radio frequency identification (RFID) tags broadcast detailed information about objects to which they are affixed. The technology is already available--consider medical tracking--to put RFIDs into food.
In the name of food safety, nutrition, and stores management (smart refrigerators would sense when we are running low on eggs) a London engineer has advocated "Nutrismart" tagging. Of course, once we consume these tags, anyone with the right receiving equipment would know what we've eaten, where we've been and when, and other information that perhaps only our doctor knew. And there is no off switch to RFID like the GPS in our cellphone. What could go wrong?
On a restaurant sign of the near-future: "Our food contains no pesticides, herbicides, hormones, or electronic devices."
