The sun was bright this morning 
And as i lay in my bed 
I smiled out at the world outside 
And then within my head 
A strange thought started forming 
As if not of my will 
What if plagues and sickness vanished 
And we stopped getting ill?  
A happy thought i told myself 
But then as these things go 
The consequences came to me 
Though still thinking rather slow 
What would happen to the chemists,  
Doctors, nurses and the rest 
If we were well all of the time 
And always felt our best?  
Wall Street would be mortified 
Pharma companies would collapse 
Unless they invented illnesses 
Or, even worse, perhaps 
They'd have to spread diseases 
So we'd need their little pills 
And all of this might happen 
If we stopped getting ill.
