I used to serve in the army and many a times we would have to sleep in different terrains and environments. My fellow comrades used to complain about having stiff necks, but I would always wake up fresh and recharged. When approached on what's the secret? I told them that since young while studying my parents will tell me to sleep over it if I am unable to grasp the concepts.
So, I have been sleeping on piles and piles of books, every, single, day. =)
my math teacher senior year of high school called it "learning through osmosis" when someone would have their head down in their book
Oh goodness! There was this one guy in my elementary school that did the exact same thing! And goodness, he ended up being a valedictorian! hahahaa
Lol nice!
