@stsopoci Very likely it is age-related, but it also means a loss of 'function' in operational memory. You should, even at age 85-95, be able to read aloud a new phone number and then press those numbers on the handset in the correct order three short seconds later.

There is such a thing as a 'busy brain' where it is lost too much time during the day in fleeting thoughts, problems, desires, news bits, little momentary chores..stuff not worth retaining, so you dump it....and then when you go to concentrate on something you need to understand....AND...to retain for at least an hour, it just ain't gonna happen.

The human brain loses ground in vascularization, blood supply, and in capacity as a result as we age. You may, not saying you are, but you may be well inside that camp by now, so...yup...it's normal, natural aging.

I just went on YouTube and did a search for 'seniors, how to improve memory' and found many example videos, but I selected this one. I have not listened to it, don't know the host/narrator....so if it's a bust, please just use it as an example of how you can do your own search and listen to several videos by people who claim to offer help with memory:
