So generic 50 mg toprol xl with mastercard, in a sense purchase toprol xl 25 mg without a prescription, you are massaging your organs by gently moving back and forth on your feet buy cheap toprol xl 50 mg on line. Listening to Your Body The theory of Chinese medicine will be examined in more detail in Chapter 12. Jane (all names have been changed), 57, came to my class one rainy day in May and told me that she was a mess. The most upsetting thing to her was the sudden onset of the pain, with no warning. She felt she could deal with it, if she had time to prepare herself mentally. The cause of her pain, arthritis and fibromyalgia, was not impor- tant at this point—her mechanism for recognizing and dealing with is was. She was able to adjust her posture and her breathing, make use of meditation exer- cises, and set herself both physically and mentally for the coming battle. The young crowd and the loud music contribute to a sense of unease and of not belonging. One of the most glaringly obvious prob- lems with our Western exercise system is that health is equated with a perfect body. Ladies, how many times have you looked at the cover of Cosmo or Vogue and sighed with envy? Did you, at that time and place in your life, really want to look like that? Guys, same thing for us, but of course, different role models—Rambo, Arnold, and the like. The problem here is the overemphasis on the external, or yang, aspect of you. Physical beauty fades in time; the skin wrinkles; hair turns gray or falls out. Keeping the ideas of the pre- vious paragraph in mind, make sure you want to lose the weight for the right rea- sons. It works from the inside out, bringing your peace of mind and positive self-image to bear on the weight issue. Again, this is the flaw in so many of the fad diets—they address the calories, but not the whole person. The calming effect of the movements leads to an overall calmer attitude toward life.
Letters to the Editor These are usually fairly short pieces of writing (two to three paragraphs) submitted for publication generic toprol xl 25mg without a prescription. Many people look down on them toprol xl 50 mg overnight delivery, which is a shame because they are difficult to do well toprol xl 50mg, and are often more widely read than longer pieces. They give people the chance to write for publication, and, if accepted, to see how their work is used. Look carefully at the letters in the target publication, and work out how long (or how short) it should be. You will have few words to play with for this so weigh up carefully what you need to say. But lists 74 LISTS can be limiting: they are one-dimensional and tend to establish links between thoughts and ideas that can be difficult to alter. Some teachers on effective writing techniques now recommend more flexible ways of planning (see branching). Literature (1) The term used to describe a piece of writing that is still read and valued, sometimes centuries after it first appeared, because of some enduring qualities that are often hard to define. It has usually been written because the writer has some kind of impulse to write. It differs from the kind of writing dealt with in this book, where the purpose is not to please the writer (or satisfy his or her demons) but to put a message across to a target audience (see effective writing). Since the quality of writing in journals is usually extremely poor (see style), this is a clever piece of marketing on behalf of the academic community. Macro-editing This refers to the under-used technique of asking one or two major questions when you are considering a piece of writing in draft, rather than throwing at it all kinds of detailed but minor difficulties (see micro-editing; balanced feedback). Traditionally magazines have been divided into two groups: • The business press comprises publications sent to specific groups, (such as doctors, lawyers, elevator manufacturers) often without charge. The basic principle of writing for a magazine is similar to that used for writing for a scientific journal: identify your market, create your product, and sell it. The best place to start is those magazines to which you subscribe because presumably you will share the interests and language of the readers. A good editor will often seek a second opinion (or third or fourth), but will do so informally. This clar- ifies your task: you have to please the editor, and not go through a panel of unknown (and therefore unpredictable) reviewers.
