The elderly women who dive for seafood off the island of Jeju, Korea, are called haenyo, which means "sea women." They are carrying on a century-old tradition that began when women realized they could bring home the seafood without paying the taxes that would be levied on men in the same profession. It is a declining way of life, which explains why the remaining haenyo are elderly. Read more about them and see more photos at Kuriositas. Link
