📜 Poem about the Brain
In uns'rem Kopf, da sitzt es fein,
das Gehirn, mal groß, mal klein.
Es denkt und lenkt, bei Tag und Nacht,
hat uns das Sprechen beigebracht.
Ein Wunderwerk, komplex und schlau,
weiß auf viel Fragen ganz genau,
was zu tun ist, was zu sein,
unser eigenes Kommandozentrum, allein.
(In our head, it sits just fine,
the brain, sometimes large, sometimes tiny.
It thinks and guides, by day and night,
taught us how to speak just right.
A marvel, complex and smart,
knows for many questions, right from the start,
what must be done, what must be,
our very own command center, solely.)
