Thank god we feel hungry!

-
Was wondering [as usual :-)] at breakfast today.

Yeah, what if we never felt hungry? Suppose there were a source of renewable energy in the human body. Would humankind have progressed to where it is today.
Isn't hunger the most promordial of drivers of human progress?

So the next time you feel hungry, thank god that you do feel hungry, and not for the food you get.
[Ok don't bombard me with hate mails for this blasphelmous suggestion :-D]
