Epidemiology - a discipline that studies the causes of disease looking at who is affected, where diseases occur, when they occur and the social, environmental, dietary and lifestyle correlates of disease occurrence. Disease - bio medically measurable lesion, or an anatomical or physiological irregularity. Dichotomous individuals are healthy or sick. The limit between health & disease is not always clear. Smoke-detector principle: the cost of not doing anything is higher than the cost of a minor inconvenience. Example: symptoms such as cough or fever are not defects but in fact are the body" defense in action. Also pain, nausea, vomiting, diarrhea, anxiety, fatigue, sneezing, inflammation, anaemia, morning sickness. To kill the bacteria instead of it killing you! The cost of not doing anything is too high. *often correlate but are not sufficient to diagnose a disorder. Darwinian concept of mental health/disorder: capacity to achieve biological goals, functional capacities established in consideration of the environment in which the individual lives.
