As a matter of fact, consider any memory you have, an activity "you" participated in. If you consider the molecular structure of your body, very little of "you" was actually there. Most of your cells are not the same cells that were present during that memory.

Time is a measurement we use for categorizing history and laying our lives out in line, but time does not have an inherent directionality, if it exists at all.
