It's interesting being able to tell how much exactly people have become programmed and how much are real. If we compare modern society to ancient Rome and Greece, it is possible to notice the main difference about public toilets. Since ancient public toilets were not private, but are mandatory now, it's rational to assume that people didn't feel disgust before, but do feel it now. Also the same goes about nudity and sex. In ancient societies statues of naked people were not erotic, they symbolized the perfection of god alike alpha bodies merely from biological point of view. Today people are ashamed of naked bodies, also naked bodies are associated merely with sex. It is still not clear if modern humans are being guided by more evolved instincts and reflexes based on logic, or if the modern human brain is the result of 2000 years of programming by religious ideology.
