Age-related learning difficulties could be attributed to the fact that we simply run out of memory space.

New York Times said:

Learning becomes more difficult as we age not because we have trouble absorbing new information, but because we fail to forget the old stuff, researchers say.

I read today that good sleep is needed to retain new memories and that the difficulties some older people have getting such sleep explains it.

I dunno.  I'm getting on there and my memory is fine.  I think you gotta exercise it just like you gotta exercise your muscles.

Wonder if memory enhancing drugs or herbals would lend a hand to this.

Side Note: I've been using Lumosity.com to assist with memory, speed, and overall cognition, those games on the site are pretty fun. It's part of the human cognition research project. Also, when Einstein died, it was said his brain was similar to that of a young man. I wonder if that was a result of his "thought expirements"?

Which could be the reason why Albert Einstein's brain looked like that of a young man when he died at 76 years of age. :)

Poor Einstein though did his great work in his twenties, got famous, and then got stuck trying to solve a problem that is still unsolved.

I've been telling my wife for years that I can't retain everything she tells me - now I have an excuse! Hooray for Science

I could use a defragging I think?

My Mom's 75 and a geneaologist. She can recount up to 13 generations of family history and stories which includes over 150 family names.

My nephew gives her computer advice (because she faithfully has given it and retrieves it online, for as long as there has been an internet) about how to delete her cookies, maintain her computer, or such. She tells him, "I don't need to know that, that's why you're here."

I'm hard pressed to decide what is the cause and effect for this. Like that whole protein ratio thing, what also changes from childhood to adulthood is how often we learn new things and have new experiences

Could be the more things we learn and the more things we experience the sharper our minds will be, and if we avoid it then our minds would dull and our memory capacity would decrease.

Like I said, to keep your brain going you need to exercise it.  I don't mean just reading things (although that helps) but leaning things.  Study something that requires memorization.  Learn something new.  Do this with the same deliberate intent that causes you to go out and take your morning walk, or go to the gym, or whatever it is you do to get exercise for your body.

If sleep is a problem (and sleep is needed to move memories from short-term to long-term memory), try meditation and prayer, in quiet circumstances, where you rehearse what you are learning, or even just periods of listening to quiet orchestral music (music with singing doesn't work for this).

My word I'm full of it today; it's just that I know it works.

Something else may pop up a few years later that suggests otherwise. You never really know.

Jesus Christ - Matthew 28:18-20 said:

"All authority in heaven and on earth has been given to me. Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age."
