Same here. Does it have something to do with exactly how the blood is flowing through one's brain at the time?
Well, I don't know, but I found it interesting to learn that when you begin thinking about something in particular, the vessels in that part of the brain dialate, so that more blood can flow through there, making your thinking easier about that topic. So, maybe that has to do with not being able to recall something at a certain moment, when you
know you know it, and that you'll be able to think of it later. I sometimes have that sense, sort of like that webpage bulletin "under construction"

. Like my brain is saying, "Not just now; come back later."
In other words, our brains "warm up", in a sense, and once the blood vessels in the area we're using are fully dialated, we're at maximum efficiency for thinking about those thoughts. I found that fascinating. So, it's actually medically proven to be good to take your time when thinking; you get better results than when you rush. That's also probably why we have to "concentrate" on certain things: because the blood has to get largely to that area of the brain before we can do our best thinking.
