Use antibacterial soap, or the terrorists win. (But don't enjoy it!)

From Publishers Weekly:

According to Ashenburg (The Mourner's Dance), the Western notion of cleanliness is a complex cultural creation that is constantly evolving, from Homer's well-washed Odysseus, who bathes before and after each of his colorful journeys, to Shaw's Eliza Doolittle, who screams in terror during her first hot bath. The ancient Romans considered cleanliness a social virtue, and Jews practiced ritual purity laws involving immersion in water. Abandoning Jewish practice, early Christians viewed bathing as a form of hedonism; they embraced saints like Godric, who, to mortify the flesh, walked from England to Jerusalem without washing or changing his clothes. Yet the Crusaders imported communal Turkish baths to medieval Europe. From the 14th to 18th centuries, kings and peasants shunned water because they thought it spread bubonic plague, and Louis XIV cleaned up by donning a fresh linen shirt. Americans, writes Ashenburg, were as filthy as their European cousins before the Civil War, but the Union's success in controlling disease through hygiene convinced its citizens that cleanliness was progressive and patriotic. Brimming with lively anecdotes, this well-researched, smartly paced and endearing history of Western cleanliness holds a welcome mirror up to our intimate selves, revealing deep-seated desires and fears spanning 2000-plus years.
