cerebrum
The cerebrum, reputed seat of sophisticated thought, is the organ humans credit for genius. In practice, it excels at replaying trivial anxieties and regrets on endless loop, robbing you of clear judgment. It can be seen as a factory for self-contradiction, churning out perplexing doubts. A dutiful janitor of mental clutter, tasked with storing every embarrassing memory. Ultimately, it's a little slave demanding more coffee tomorrow, groaning under the weight of sleeplessness and creative despair.
