The Evolution of a Senior Isn't Quite So Funny in a World Full of VAM

I found the above chart in a 1945 City Yearbook several years back.  The kids who created it had a great sense of humor and clearly a lot of insight into "the evolution of a senior."  It's brilliant.  In a world full of VAM, it's not quite so funny.  God help those of us who may have senior classes--because statistical formulas by the likes of Chetty surely will not.  Senior teachers will become the fall guys for "senioritis"!  It doesn't take a genius or a formula with thirty-nine variables to recognize this simple fact!
