Unglued

The mind holds many memories
Which cling to it like glue,
A storehouse of forgotten facts
You hardly knew you knew.

But as we age, the files get filled
And when we try to store
New knowledge or experience,
There isn’t room for more.

And that explains why I just read
A novel I’d once finished,
A little hint to let me know
My brain cells have diminished.

For just like old adhesive
Will no longer do the trick,
There comes a point within your brain
When nothing new will stick.
