Brains are really weird. Imagine, right now, whatever you're doing, just imagine your brain sitting inside your head reading this. It's also making sure that you're breathing, that blood pumps around your body and that you're producing saliva.

Imagine playing football. Your brain is making thousands of calculations all at once. Making your legs move, your heart pump, your lungs inhale and exhale, cooling your body down with sweat. It's also judging how far away each person is, how fast they're going in relation to the ball, creating potential plays, judging the bounce of the ball and making decisions.

Brains also create our own personal likes and dislikes. I really hate it when you go to a cafe, and they serve you a latte in a mug and not a glass. Why do I hate that? Some people don't care. But my brain doesn't like it. I don't care if some people smoke cigarettes. Some people do. You can say because we all have personal opinions shaped by experience and upbringing... but why? Why do certain negative experiences put us off things for the rest of our lives? Because our brains say so.

Brains retain thousands and thousands of memories; including stuff like the alphabet, maths, memories with your family, dates, books, movies, tv shows, quotes, ideas, music lyrics, how to light a candle, what colours go with which, how to use a computer, mobile numbers, how to put your shoes on or apply make up, which shampoos make our hair gross and which bands we don't like. It remembers people and where we know them from. When their birthdays are. Who they have a relationship with. What they've done.  

It also works while we're not even awake. Fabricating dreams and growing your hair and nails, making you rotate to keep you comfortable. Moving muscles to make you do so successfully. All the while, still making sure you're breathing and pumping blood and regulating your temperature.

It tells you when you're itchy, when something hurts and when something feels good or tickles. The brain makes us feel sad when someone makes us feel like we're not good enough and angry when someone does something that it tells you that you don't like.
