I think the brain continues to process things as we go along. We may not even be aware of it. I think it likely our brains develop new coping mechanisms as we go along.

Not exactly like forgetting, but rather a brain saying "okay, I can handle this".

I guess breaks could really help that processing, because there would be a stop to the endless poking and prodding at the brain. I mean, you've got to give it a chance to work every now and again right?

I'm reminded of my all time favorite quote from the Homer Simpson - the buddha of my generation:

"Okay brain, I don't like you and you don't like me, but let's just do this and then I'll go back to killing you with beer."
