Like Velcro

My brain was once like Velcro; Each tidbit added stuck And waited there, accessible For me to find and pluck. But all the space got taken; The Velcro’s been replaced By ancient masking tape from which The glue has been erased. So new additions do not stick And cannot be retrieved. Had I been warned when I was young, I wouldn’t have believed. Yet all things have their limits And this, too, goes for the mind. The more we age, the more we leave What we once knew behind.
