But there is an extreme which perhaps has not been thought of and for which happily I have an example that will illustrate what I want to prove.

I know a woman who was, so to speak, daft on the subject of health.

She attended to all points of health with such minute detail that she seemed to have lost all idea of why we should be healthy.

One of her ways of over-emphasizing the road to health was a very careful mastication of her food.

She chewed and chewed and chewed and chewed, and the result was that she so strained her stomach with her chewing that she brought on severe indigestion, simply as a result of an overactive effort toward digestion.
