After just hitting the big 5-0, I’ve been thinking a lot about what truly differentiates “young” from “old.” I believe that -- if we’re lucky -- we never outgrow the curiosity of a child. I want to know what makes it tick, who influenced whom, what came before and what happens after. Thank goodness public broadcasting is there to help satisfy all the intellectually, scientifically, politically and generally curious minds out there, regardless of age.
