I suspect that people operate with the wrong model of memory -- the
brain isn't a "recorder", and I'm far from certain we have enough room
to really "record" fourty years of experience faithfully, let alone
140. We certainly do forget large chunks of the "less important" stuff
and possibly so that there will be "room" for the newer stuff.

It might suck, but I have come to accept it. If it bothers you a lot,
I suspect a diary might be a simple low-tech way to deal with the
problem.
