Everyone knows (or should know) that everything that happens are just electrical signals interpreted by our brain. You tasting the food you are eating is just your brain interpreting what your taste buds have sent it. You seeing this text is just your brain interpreting what your eyes send it. And all humans can remember things, correct? So why is it, that we remember some things, but not others? And what exactly makes us remember things? Do the electrical waves stay in our brain forever? Or do they sort of write to our brain permanently, like a hard drive? If so, why can't we remember everything? It can't be that our brain has a maximum capacity, as we only use 10% of it. This is some confusing stuff, that I for one, wouldn't' mind finding some answers to.
