From shadows to the stars

Have you ever noticed those facts which begin with "Did you know that...?". What I have observed is that most of those facts are utter crap. I have come across some so called facts about the human brain and how it functions in my lifetime. I have marveled at these for quite a long while, but suddenly, those "facts" have been crushed.

You are expected to just sit there and stare into space. 2) Okay. Don't let me leave until the regulated time. But at least, let me sleep! But, no. Sleeping in the exam hall is considered as a sacrilege. "How dare you sleep in the exam
