How did 21P make a song about growing old that’s just as uplifting as it is depressing?

And I will say that we should take a day to break away,
From all the pain our brain has made,
The game is not played alone.
And I will say that we should take a moment and hold it,
And keep it frozen and know that,
Life has a hopeful undertone.

This song cheers me up every fucking time I hear it.
