Social Constructs

Now that you all know how to shake hands lefty, and that some of us aren't so ambidextrous as we thought, we can begin to look at how society constructs our realities from handshakes to cannibalism.

After reading about the survivors of the F-227 crash in the Andes and the ways they had to adjust their concepts of reality to allow themselves to eat the bodies of the dead and experiencing how odd it feels to violate your societal rules on handshaking, I am sure you can think of many other "realities" in everyday life that you and others never question. Many of these unquestioned realities are constructed by our society for us and with little or no thought given to it by us. Sometimes learning these beliefs and activities are considered part of the acculturation, growing up, fitting in, or being socialized.

What other activities do we do that are not scientifically essential for our survival but we do them practically all the time??? Blog about some examples. Why do we do these things? How does society teach us to do them? What happens if we violate these constructs? Why?
