Adrenaline

Organic and Mineral,
Man and Rock.
Grasping, gripping,
Pulling, pushing.
The rush of the height,
The wind drifting over you.
Reaching, scrabbling, air!
Falling, infinitesimal time,
The jerk of the rope gone taught,
A call of reassurance from the belay.
Finally up, safe, weak,
Shivering from adrenaline shock.
