Memory

So today I was getting a glass of orange juice (Iknow, random, but it eventually connects to every thing else). I balenced the carton on top of my head while I went to get a cup. Then, when I was ready to pour it, I forgot where it was. Luckily it fell off of my head then, so I got my orange juice.
That brought me to the question. Where would we be without memory?? If we did not have the ability to remember things, we would fail all of our tests, wouldn't be able to remember what we learned. And, if you bring It back far enough, we wouldn't even remember to make fire, cook, play Monopoly, people would have never figured out how to make another car. Just think. Humans would be nowhere right now without memory.
