T-Rex: One day Sam read that we only use 15% of our brain! That's not a real fact, Sam! We use all of our brains!
T-Rex: But Sam couldn't hear me!
T-Rex: And she was hard at work trying to unlock the full potential of her brain!
T-Rex: Amazingly, she SUCCEEDED. While she couldn't ADD brain power, she could learn to CONTROL it better. And Sam, unlike everyone on Earth who had been born before her, now had FULL CONSCIOUS CONTROL of her entire body! NOTHING happened with her body without her willing it to be so! She was, at last, fully in control of her brain AND her self.
Utahraptor: Oh wow! What'd she do?
T-Rex: Oh, she died. She's super dead.
T-Rex: She was so frantically focused on making sure that her heart beat that she forgot to deconstrict some blood vessels feeding her brain, which pushed her into unconsciousness, at which point every single system in her body instantly stopped, because she wasn't awake to tell it to keep working, the end.
Banner: The only reason you're alive is that your body doesn't actually let you control it
T-Rex: Oh, hey! The banner I bought advertising the moral of my story just arrived!
