There's a pretty wide gap between the level of hygiene required to prevent something like cholera (hint: basic plumbing to move your poop away from where you live) and the overly compulsive level of cleanliness I see amongst so many today. Numerous household cleaners with crazy anti-bacterial formulations, people obsessively covering their hands with alcohol-gel. These products are driven more by advertising and people's need to find things they can control in their lives than they are preventing any real amount of disease.
