Abstract  

Johnny Mercer had a hit song a few decades ago in which he admonished us to accentuate the positive, eliminate the negative, hold on the affimative and to have nothing to do with in between. This seems like good advice, but as is the case with most good advice it is rather hard to follow and not always applicable.
