I rely on my memory much less than I used to. Not only am I getting older, but I've also read a great deal about how memory works. We reconstruct events rather than simply replaying them on a recorder. Therefore, what we THINK happened is often a mish mash of actual memory and reconstructions to fill in the gaps. So honestly, I don't really know what I can reliably say to add to the discussion. David's account is much more recent. And as was brought up, we often can't even rely on a first hand account. It's been literally 40 years now (this fall) since 1840 aired.
