people are born with three different iris colors:gold one, silver one and bronze one. People with bronze are slaves, silver normal and gold ones are basically kings. You can choose what color of your eyes you want. Do you choose: A)Bronze eyes? (very useful to the ecosystem, and much more productive and healthy) B)Silver eyes? (basically normal) C)Gold eyes? (Bronze are your slaves and you basically dont need to move, but there is a high risk of getting fat, lazy and you have a lot of things to do, since gold ones have to constantly maintain the world) type A for bronze, B for silver and C for gold
