You are yogurt.
You take a scoop of the parfait, full of oats and raisins, and quickly shove it into your mouth as you continue your frantic work to finish a paper due in less than four hours on a book that you have never read. All the while, you are yogurt.
You see, when you eat something, your body absorbs it. It takes the good stuff in that yogurt, and it puts it inside of you. These yogurt goodies then replace the older coffee goodies from earlier today. You now have yogurt stuff flowing through you. You are yogurt.
So while you are worrying about a paper that is due, on a subject you know nothing of, find some solace in the fact that you are, in some small way, yogurt.
