Is walking ever purposeless?

Everything has purpose, even seemingly aimless wandering. An article about the benefits of purposeless walking because it facilitates creative thinking. That sounds purposeful to me. Such meandering still has other benefits. In controlling my glucose levels, meandering around zoo pathways with my granddaughter, as low intensity as it was, still drove my higher post-meal levels to fasting levels. It just took a little longer than the higher intensity round of Nordic walking.
