Williams uses a similar device here. Doctor Bishop is brought into the argument. She is not just a doctor, but a consultant dermatologist. Although we do not understand the jargon doctors use, we are always impressed by their use of subject-specific language. It is very interesting to note that Williams, afraid perhaps of losing her audience by using too many expressions we do not understand, eventually gives us one or two layman's explanations - as in the case of elastin and of collagen.
Industries are commercial enterprises by means of which people make money - or, at least, hope to.
Other occupations, where the profit motive is supposedly of the most minor significance, are never referred to as industries. All of these professions are primarily regarded as providing a service for the benefit of the community. She leaves us in no doubt about her attitude towards her subject. In the case of Jane Horwood, earlier, we were asked to feel sympathetic towards her suffering and asked to understand the fears that led to her taking the wise decision to put an end to her habit. How reasonable, thoughtful and moral she sounds, giving up suntanning to protect her unborn child.
