Purely physical, you were (are) the rush of blood to my head.
The pounding in my chest like I've run that bloody mile minus the three and a half laps of that bloody track.
The pulse in my thumb sometimes when I've jammed it or perhaps split it and it sounds just like when I press my fingertips against your chest.
My head is spinning but that's daft.
You cannot analyse this feeling.
You say it's just a weakness that we're only human but how else would we reach this heightened sense of longing and why else would I be staring so very intently at you?
Blood, sweat and tears and heat and heart.
Which is which and who is who is beyond me.
