The Old Testament observes that “all flesh is as grass.” Religions have addressed the question of how one should live with the awareness of inevitable death. Often the answer has been based upon the vision of a life beyond death.

  • In this opening chapter, we outline some of the most influential (and most contested) definitions of health, and approaches to health promotion. Although some success has been claimed for health promotion interventions, in general the results to date have been modest: for example, safer sex campaigns in preventing HIV infection among gay men.

  • Science tries to explain a very complicated world. We are surrounded by very many objects, moving around, reacting together, breaking up, joining together, growing and shrinking. And there are many invisible things, too - radio waves, sound, ionizing radiation. If we are to make any sense of all this, we need to simplify it. We use models, in everyday life and in science, as a method of simplifying and making sense of everything we observe. A model is a way of explaining something difficult in terms of something more familiar. For example, there are many models used to describe...
