Well, when we're younger our brains are more receptive, especially in the early years when our brains are knowledge sponges, absorbing information rapidly and etching it into our memories. This is one of the reasons it's much easier to learn languages as a child than as an adult. By the teen years, once the brain sets into a pattern, it becomes increasingly difficult to adopt new things i.e. accents, dialects, pronounciation, and in some cases new ways of thinking altogether. The human brain really is a wonder.
I love recognizing all the stuff we saw as kids

It brings back great memories and feelings from those days.
