Haven't any of these overpaid, overstuffed researchers ever read any Heinlein. In Methuselah's Children, Lazarus Long posed the same question to his much younger (and smarter) friend, Andrew Jackson "Slipstick" Libby, Andy explained it as simple as you like. We experience events linearly as time goes on, but our brains correlate each event with the accumulated total of all other events in a geometric fashion. Accumulation of experiences progresses linearly, but the storage required and effort needed to retrieve the memory and all its associated memories grows exponentially.
Unfortunately, the book ended before Andy published a solution to the problem, which he claimed was definitely solvable.

Which is why our brains do compression -- they find memories with a common pattern and condense them.. sort of like doing a Lempel-Ziv pass. Oh, and it runs while you sleep.

Its so good, you don't even realize it's there.. just ask a friend who's had a major seizure or amnesia. Sometimes one of the indexes gets partially lost and chunks of memory become inaccessible until they're reconnected via access through another index.
We can program with only 1's, but if all you've got are zeros, you've got nothing.

Didn't Lazarus mention something in a subsequent story, maybe "Time Enough for Love," that he was using a method of tiering his memories. I wonder how someone consciously does that and how you master the technique.

I believe that you're right. Now I'm going to have to dig that one out and reread it again. I'll let you know when I master the technique, if I remember...

Balderdash! I take it this Ramscar chap is a social 'scientist' of some kind and not a neurologist because this is a perfect description of precisely how human memory doesn't work! Provided the structure and chemistry is not damaged in some way (Alzheimer's being the chief culprit these days) brains simply do not work slower at all. The notion that we have to sift through all the extra clutter to get to the good bit is just nonsense.
There appears to be a reduction in cognitive performance with age but this is part self-fulfilling prophecy (how many times a week do you put cognitive errors down to getting old, having a senior moment, and so on?) and part simple misreading of the evidence. Completion of IQ tests do suggest that older people take longer reaching answers but attributing this to 'slowing of the brain' is almost certainly nonsense. The delay has much more to do with psychology than neurology. Age brings caution, responsibility, and (largely fuelled by that self-fulfilling prophecy) a greater involvement in testing oneself against norms. Older people simply care more and therefore take greater care in cognitive tests. Thus the slowdown is the result of self-checking and greater investment in protection against errors, not some weird, chaotic search through a memory attic stuffed with junk.

Ageing causes changes to the brain size, vasculature, and cognition. The brain shrinks with increasing age and there are changes at all levels from molecules to morphology. Incidence of stroke, white matter lesions, and dementia also rise with age, as does level of memory impairment and there are changes in levels of neurotransmitters and hormones. 
Conclusions: 
That the brain changes with increasing chronological age is clear, however, less clear is the rate of change, the biological age of the brain, and the processes involved. The brain changes that may affect cognition and behaviour occur at the levels of molecular ageing, intercellular and intracellular ageing, tissue ageing, and organ change.

There have been times when I have felt so overwhelmed with memories that I wish I could remove them and completely forget. I think the emotional memories are the most difficult to deal with, and I have a better understanding now of the expression that death would be welcome. I think it's something that few of the futurists/technologists understand, that at some point, you just want to turn off rather than keep living on and on, acquiring more and more memories. Emotional memories is also something that I don't think neurobiologists (or even psychologists) understand or appreciate, how crippling they can be, and we all do acquire them. While I know people that seem to live in a constant state of bliss, seemingly only remembering the positive emotional places, I for one am not one of those people and must consciously redirect my recollection of past events toward positive events to balance out the negative ones.
Hmmm...that wandered a bit OT, what were we discussing?

Actually, that's exactly it. You remember the most what you have emotional ties to. That's why chicks remember EVERYTHING about a relationship, they're so emotionally invested into it. I used to be the same way man, way more emotional than a chick even, and the trick to getting over it is to just realize it's stupid to be emotional about most things in life. Grab your balls and laugh it off. Once it's no longer a big deal nature will take its course and you'll let it go naturally.

I'm with you death is more welcome the older I get.
I've had a long hard life, I've lived it to the fullest but there is a lot of bad stuff that has happened to me and depression is an unwelcome part of my life. There are times when I've said that I've had enough but something has driven me to go on.

Great, I can use that instead of "geezer moment"!
I think that the wandering room-to-room thing is an "Out of Memory" problem while my background processes try to compact and free up by deleting useless information. Unfortunately, these processes are buggy as I swear my head is full of useless crap. I should switch to an Apple OS so everything gets dumped with every upgrade (useful or not!)

Shades of Johnny Mnemonic. So, do I need to dump the old storage to free up cache for the more frequently accessed data or do I need to buy some auxiliary memory for offloading?

If that is the reason for cognitive decline, I may be at an advantage as I get older. My brain is far from full because I suffer from a family malady called CRAFT.

Unfortunately the brain is not fully recursive NN. More pathways appear as they are needed. So the more you used it, the more you get to fully recursive, so the lesson is use your brain more.
P.S. That doesn't mean to store more information. You can keep CPU at 100% usage without using any memory.
