here is an excerpt from clive james "vertical envelopment" a rather log but brilliant poem...
Taking the piss out of my catheter,
The near-full plastic bag bulks on my calf
As I push my I.V. tower through Addenbrooke’s
Like an Airborne soldier heading for D-day
Down the longest corridor in England.
Each man his own mule. Look at all this stuff.
Pipes, tubes, air bottles. Some of us have wheels.
Humping our gear, we’re bare-arsed warriors
Dressed to strike fear into the enemy,
But someone fires a flare. Mission aborted.
On the airfield, the chattering Dakotas
Have fallen silent. Jump postponed again.
Stay as you are. Keep your equipment on.
When cloud and wind are OK in the drop zone
We hit the sky and leap into the dark.
Meanwhile just hunker down and get some sleep.
Look on the bright side. Everyone’s still here.
