This is a really hard concept for me to explain. I have been thinking about it for a little while. It struck me, that so much of who we are depends on remebering what we do, and how to do things. Now, if our memory was shortened to a couple of seconds, leaving us only the capacity to remeber to breath eat drink etc, would what we do exist? Ie, if there is noone there to witness what we do, record it a present it as evidence that it has been done, how do we know that it has ever been done. ASctually more than us knowing, coz that means it only exists to humans, but what I guess I mean is, what would we be? we would loose so much... so much i dont think we we even be human. Kay, i explained that reallly badly!
