ENVIRONMENTAL PROBLEMS Our environment is constantly changing. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters people need to be aware of what types of environmental problems our planet is facing. Current environmental problems make us vulnerable to disasters and tragedies, now and in the future. Unless we address the various issues seriously we are surely doomed for disaster. Current environmental problems require urgent attention. 1
FUNDAMENTALS-- FIRST AND FOREMOST THE MINIMUM EFFECTIVE DOSE From Microwaves to Fat-Loss Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away. --Antoine de Saint-Exupéry A rthur Jones was a precocious young child and particularly fond of crocodiles. He read his father's entire medical library before he was 12. The home environment might have had something to do with it, seeing as his parents, grandfather, great-grandfather, half- brother, and half-sister were all doctors. From humble beginnings in Oklahoma, he would mature into one of the most in uential gures in the exercise science world. He would also become, in the words of more than a few, a particularly "angry genius." One of Jones's protégés, Ellington Darden PhD, shares a prototypical Jones anecdote:
T h e office atmosphere of Fox 2 0 0 0 was a fascinating place to study the ways of power. In the past I h a d been aware o f places like it, but as a story analyst I h a d not been inside those meeting rooms where the decisions were taken about the writers, the stories, and the movies made from them. Power flows in those rooms like hot lava, and until I worked at Fox 2 0 0 0 I had only heard it rumbling. Now I was standing hip deep in it. It was the most adult environment I had ever been in, run on unspoken but rigorous principles of personal responsibility. N o whining allowed, no excuses. And the same fierce intensity was applied to the stories. Every concept, every comment, every suggestion had to pass the most stringent tests of common sense, logic, and show business instinct. I had the good fortune to work with some of the best story brains in the business, foremost among them being Fox 2 0 0 0 ' s founder Laura Ziskin,
more than a clump of robin red breast feathers placed there. At the same time, it will virtually ignore a perfect stuffed replica of a male robin without red breast feathers (Lack, 1943). Similar results have been found in another species of bird, the bluethroat, where it appears that the trigger for territorial defense is a specific shade of blue breast feathers (Peiponen, 1960). Before we enjoy too smugly the ease with which trigger features can trick lower animals into reacting in ways wholly inappropriate to the situation, we should realize two things. First, the automatic, fixed-action patterns of these ani- mals work very well most of the time. For example, because only normal, healthy turkey chicks make the peculiar sound of baby turkeys, it makes sense for mother turkeys to respond maternally to that single cheep-cheep noise. By reacting to just that one stimulus, the average mother turkey will nearly always behave correctly. It

life. And the best news of all is that they are completely under your own control. ■ THOUGHTS, FEELINGS, AND DESIRES You are a complex bundle of thoughts, feelings, attitudes, desires, images, fears, hopes, doubts, opinions, and ambitions, each of them constantly changing, sometimes from second to second. Each of these elements of your personality affects the others, sometimes in unpredictable ways. Your entire life is the result of the intertwining and interconnecting of these factors. Your thoughts trigger images and pictures, and the emotions that go with them. These images and emotions trigger attitudes and actions.Your actions then have consequences and results that deter- mine what happens to you. If you think about success and confidence, you will feel strong
