What are the things you find amazing about the world? What's your biggest mindfuck?
I'll go first (no particular order):
The brain! We actually have a lot to learn about it. How people's characters are made, how they behave, how the brain can often heal itself, how substances affect it.
Dreams and their reflection on reality (or not).
People surviving the 'unsurvivable'.
That I could die at any moment, or live for a really long time.

How big the world is and time zones - while I am here, x people are asleep, y people are being born. People are doing opposite stuff at the same time.

Someone on the UK version of "Life In A Day" said that he believed in God because only He would have created for discovery a system of science that would seem to disprove His own existence. Not religious, but that was amazing.
