Oh, they're just a time where my mind is allowed to run free and not be consumed with responsibilities or overwhelmed by screens and social media - one of the only times when I don't feel guilty for not fixating on what I should be doing. Also, they're a reminder of the tangibility of the material world and that I have a body; I'm usually lost in my own head and neglecting my body or treating it poorly in service of whatever I want to do, like making music or watching something or whatever, so activities where I directly deal with my body can be supremely refreshing.
