An excellant limerick, and you are correct, one of a very few serious ones out there. I liked it a lot, at first for its simple and clean cut form, and then for the moment of intense thought that followed it, like a great wine, this is a poem to be savored, even if its only a sip.
only thing i would change is if to of the. Its kinda hard to understand. But yes, short and sweet, just the way i like it:) Makes you think a lot...

I very much agree with the description--although I think it is wrong in saying it's wasted. . . poetry is never a waste. I typically find limerics rather shallow...but this one holds a sense of deepness. Well done.
