As I get older I find I remember fewer details unless I really concentrate. It may be because my memory is not as powerful now, or that fewer things get past the filter between shot-term and long-term memory, because fewer things hold my interest long enough. I have lost much of my ability to remember strings of numbers (phone numbers in particular), because I never, ever practice it, letting electronic devices do it for me instead.

Don't I know what you mean. So, I think I am asking why this is so. Does something cause a breakdown in memory in our brains? And if so, can something help our brains to remember more. I am thinking perhaps something chemical.

Obviously, if we knew, we would all be ingesting large quanties of the chemical. I am simply curious to what science might theorize or is working on currently regarding memory.
