1. WHY DO I REMEMBER THINGS?

Every times you experience something now, electrical charges fire through the white matter in you brain, creating chemical links that form a network of pathways out of neurons . Your memories are stored in these connected neurons,and the connection becomes stronger and expand into other neurons with repeated exposure to the new experience . Practicing a song in the guitar makes the same neural networks fire again and again, becoming stronger and thus making the song easier to play. Spending time with a new friend reinforce old connection and build new ones as you learn about your pal's habits . As you learn and gain new memories your brain's structure changes and makes new connections .The brain you have today will be different tomorrow.

LONG-TERM: Experiences move from short-term to long term memory when they're                    repeated or accompanied by meaningful emotion and significant sensory input . Scientists believe your brain has a limitless capacity for longterm memories ,but sometime you can't recall a particular detail without help from sensory clues or the recollections of friends involved in the event Scientist blame such forgetfulness on a flaw in our ability to retrieve memories --a flaw that nonscientists call  "brain fart."

Each yawn pumps air into sinus cavities in the head, cooling the brain in the process. And because the brain and body are slightly warmer just before bed, we tend to yawn when we're tired
