Hollow Existence

The above images are rough test shots from a side project I have right now that coincides with several of my ideas presented for the series 'Sapien Aurum.' For me this project has to do with the creation of a pop-science fiction myth, a society of people engineered, no longer capable of the ability to experience illness, suffering, pain, sorrow. Chemicals exist with in the water system to help aid in the populous' 'well being' as well as keep them numb. What would these people look like? If the experiences that are essential to human development are denied what, if anything, can these people be expected to amount to with such a hollow existence?
