It is very striking that phrase that you say that we go through life hunched over instead of looking forward and up.
Thanks for passing on that song, I don't understand it but I like the rhythm.
I think people slouch as they walk because they are immersed in their thoughts that are increasingly negative, they want to hide as they walk, to disappear.
I like that effect of the sky with the aurora borealis, I would like someday to see that aurora in person.
It is indeed like you say if it comes to the way people walk. I am not sure if they all want to hide, perhaps they also are scared or feel uncomfortable. The man in the song named Sammy is told to look up in the sky and don't be so shy.
