Reality is not real. Your world is a prediction. Every sight, sound, and touch you experience is the result of calculations your brain makes before reality even reaches you. It fills in gaps, fabricates details, and even alters time itself so you feel like you’re in control. But if everything you know is an illusion… what does that say about you? What does it mean for your choices? Is there even free will?

    All emotions are just chemicals, to trigger behaviours that we evolved (as social animals) for.

    Happy – rewarded for doing a thing beneficial to the self (making tribal connections, eating, sex, etc)
    Sad – punished for making a mistake (losing a friend, going hungry, not mating, etc)
    Angry – identifying a threat (tripping over that thing yet again, betrayed by a tribe member, etc)

    There are logical reasons for each emotion and therefore chemical/hormone released.

    Hmmmm makes sense. Makes you realise if you've played table tennis or another sport, you're making a decision to hit the ball back but in terms of absolute positioning etc you're not conciously deciding every little movement.

    And as for walking, it's like the knee jerk thing, or breathing. Our bodies have soooo many autonomous processes involved that we have no or little control over. Pretty freaking cool.

    From the beginning there are “blind spot tests” where you tilt your head until a dot on a grid becomes not a dot but not part of the grid because that’s what your brain thinks should be there
