For some reason, whenever I think of shepherds, I can't help but envision a guy with a beard, wrapped in a long flowing robe and holding a tall pole with a hook. It's not exactly that way anymore. The Swiss research group Kora has begun outfitting sheep with heart rate monitors that, when predators like wolves approach, register blood-pressure spikes that are then texted to the shepherd, summoning him to the scene. We can only assume that means today's shepherds can chillax with a beer while watching the game... until he gets a text that reads: Need U Now!
