Reminds me of a tale here in South Africa. An ostrich farmer contracted an electronics company to develop a product to determine which of his ostriches were sick. The company realised that a sick ostrich do not eat, and as such developed a neck band with a tilt sensor, to detect which ostriches were not eating. Great, problem solved. Except now you have to seperate the sick ostriches from the healthy ones. And the farmer said he will put food in a connected camp, and as the ostriches move between camps, he will seperate the sick ones from the healthy ones. Except the sick ones weren't interested in food, and thus automatically stayed behind in the camp, also negating the need for the original electronic neck band.
