My granddaughter is keen
To manipulate genes,
Her research labs with fruit flies abound.
When I asked how she knows
That whatever she does
Has effect, she said she can tell by their sound!
It occurred to me then
Would it function with Man?
Could a doctor determine our ills
Or the cause of our itch,
As we change our pitch,
And prescribe the appropriate pills?
And if we sing off tune,
Does it mean our immune
System is on the blink?
In such an event
I'd be glad to consent
To a “blind test” in a short wink...
