Earrings were invented as a neccessity to the fishing industry in 1472, as a primitive way of weighing fish.
Acurate weighing could be obtained by balancing fish on one side and a weight on the other.
Women were found to be the best people at balancing the weight, as men would try to turn their heads in an effort to eat the fish or the weight. The change from tool to fashion accessory began as a result of ever-more extravegant weights, particularly pearls, and more accurate measurement techniques.
