2 days to IB exams:

My heart is back to it's old tricks again. The chambers beat hurriedly, like they are tapping their feet anxiously waiting for something to happen. I feel the flow of blood around my body increase in speed, little jetstreams coursing through minute-far-too-small veins and arterioles which get faster and faster each passing minute.

It is like the anticipation of waiting for a lover that you know will leave you.
