That doesn't work the other way round. A duplicate of me up to 16:51 GMT 20 mar 2006 could suddenly start observing them. > A true duplicate of you will have had exactly the same > experiences (magical ones and all others) as you had. > It might be that your futures will differ but as long > as your are duplicates you will experience no difference > and as soon as you will have a different experience you > will no longer be true duplicates.

I can remember my past selves' experiences, although they are more different to my present self than some of my other-world counterparts. You might point out that I can only remember because my present self has memory-traces that were laid down by my past selves. But that is to assume that causality works in the common-sense way, from past to future, and not across worlds.
