Remember those laundry detergent ads from the seventies and eighties in which an exhausted housewife would scrub her husband’s blue shirts in vain to remove the dreaded “ring-around-the-collar”? Those ads were broadcast often and repeatedly. Collar dirt must have been a serious problem back then.
But now, in the twenty-first century, we don’t see such ads anymore. Does this mean that we have finally beaten the scourge of ring-around-the-collar? This, surely, is proof of the betterment of mankind.
