In one of those funny pensive moments, I was resting my head on my right hand. My index finger just happened to be lightly pressing on my temple, and I suddenly felt my pulse throb lightly beneath it; I’m not sure why, but I stopped for a second to pay attention to the hint of anatomy, something familiar and simultaneously alien. It suddenly dawned on me, as I listened in, that what I was feeling was not a throb or a pulse, but a wave. The life and movement of the blood through my veins. It’s a great feeling, to lift the veil of an assumed abstraction, and find a more meaningful layer underneath.
