Lyric discussion by jf998247 

Aside from the obvious meaning (starving child), Harry was too much of a lyrical poet to simply leave it there.

The greater metaphor is the human condition itself.

We are born with the potential for happiness (the "promise under the sun") and in our childhood we actualize that potential. But this is only because we are unburdened the bitter truths of life that time teaches us. By our "seventh day" (end of our childhood), we understand pain, and loss, and hunger. With the dream now beyond our reach forever, we cease even to weep for our losses and learn how to simply "fall asleep" in our lives and stop caring or feeling just to avoid the pain of a reality we cannot change.

By our "twentieth day" (around 3x the end of our childhood, so the onset of middle age/retirement) we are suddenly cut off from our only source of support and love ("Mama" being our families, our friends, our jobs, all the things that define us as living people) and cease to have any purpose at all. Our bodies and minds slowly fail with age, we become too weak to cry or move to resist the coming darkness of death.

The final question: "Why is there nothing now to do but die?" may as well be "Why does human life come full circle like this?" We begin strong and happy but ignorant, became cold and cynical in order to function once we realize the truth of existence. Now as we weaken and the end draws in sight, we realize suddenly that we've never touched that "promise under the sun" and never will, and with that final knowledge of inescapable failure, we yearn again to cry out like children against the unfairness of it all, and yet we no longer have the strength.
