Human beings dream of the type of time travel we see in the movies – well, maybe not in Primer. That film succeeded in making time travel look complicated, dreary, and so not sexy. Although we don’t yet have a machine, drug, or app to traipse up and down the timeline at will, we can travel to the past through memory. I took such a trip the other day when I walked into my parent’s bedroom, saw my Mom cleaning out her dresser drawers, and suddenly I was six-years-old again.
