Just yesterday while listening to NPR, I heard a medical researcher, discussing at length the detriments of lack of sleep, on the overworked Residents and Interns, who commonly work 2 thirty hour days, each week while in training.
Over 10 years ago, I did my own research and discovered PVS; the Persistent Vegetative State.

Persistent Vegetative State

There’s an all pervasive condition
Rampant in medicine today,
It crosses all sociological boundaries
I’m concerned that it’s here to stay,
Overt in the overworked intern
To become concealed at a much later date,
Abbreviated as P.V.S.
The persistent vegetative state.

There’s a glazing of the eyes
When information must be extracted,
The mind just a jumble of synapses
The thought waves hopelessly impacted,
No cure has yet been discovered
To treat this unfortunate bunch,
Though, there’s a cottage industry developing;
They make a great planter, at lunch.
