Subject: Re: Sgt Pepper
I’ve known for a long time that there is an ever diminishing knowledge of the past (in all things: historical events, art, history, etc.)

Floyd Dominy, the Director of the Bureau of Reclamation during its era of big dam building projects, said that people's memories were a generation long, meaning that, though his attempt to build a dam in Grand Canyon had been defeated, within a generation's time it could be accomplished. Fortunately he was wrong about that specific case, but I do think he had a point about human memory.
