Much in the same manner ought that oligarchy to be established which is next in order: but as to that which is most opposite to a pure democracy, and approaches nearest to a dynasty and a tyranny, as it is of all others the worst, so it requires the greatest care and caution to preserve it: for as bodies of sound and healthy constitutions and ships which are well manned and well found for sailing can bear many injuries without perishing, while a diseased body or a leaky ship with an indifferent crew cannot support the [1321a] least shock; so the worst-established governments want most looking after.

Systematic activities to prevent or cure health problems and promote good health in humans are undertaken by health care providers. Applications with regard to animal health are covered by the veterinary sciences. The term "healthy" is also widely used in the context of many types of non-living organizations and their impacts for the benefit of humans, such as in the sense of healthy communities, healthy cities or healthy environments. In addition to health care interventions and a person's surroundings, a number of other factors are known to influence the health status of individuals, including their background, lifestyle, and economic, social conditions and spirituality; these are referred to as "determinants of health." Studies have shown that high levels of stress can affect human health.[15]
Fruits and vegetables work their magic in several ways. First, they provide heart-healthy nutrients, including fiber, antioxidants, potassium, B vitamins, and vitamins A and C, explains Cynthia Sass, a registered dietitian in private practice in Los Angeles and New York. And nonstarchy vegetables—from spinach to broccoli to peppers—are low in calories and carbohydrates too, helping keep weight under control. Not to mention, veggies supply prebiotics, nondigestible carbs that serve as food for beneficial probiotic bacteria.
Long-term care (Pflegeversicherung[36]) is covered half and half by employer and employee and covers cases in which a person is not able to manage his or her daily routine (provision of food, cleaning of apartment, personal hygiene, etc.). It is about 2% of a yearly salaried income or pension, with employers matching the contribution of the employee.
Recently (2009) the main representative body of British Medical physicians, the British Medical Association, adopted a policy statement expressing concerns about developments in the health insurance market in the UK. In its Annual Representative Meeting which had been agreed earlier by the Consultants Policy Group (i.e. Senior physicians) stating that the BMA was "extremely concerned that the policies of some private healthcare insurance companies are preventing or restricting patients exercising choice about (i) the consultants who treat them; (ii) the hospital at which they are treated; (iii) making top up payments to cover any gap between the funding provided by their insurance company and the cost of their chosen private treatment." It went in to "call on the BMA to publicise these concerns so that patients are fully informed when making choices about private healthcare insurance."[50] The practice of insurance companies deciding which consultant a patient may see as opposed to GPs or patients is referred to as Open Referral.[51] The NHS offers patients a choice of hospitals and consultants and does not charge for its services.
Just as there was a shift from viewing disease as a state to thinking of it as a process, the same shift happened in definitions of health. Again, the WHO played a leading role when it fostered the development of the health promotion movement in the 1980s. This brought in a new conception of health, not as a state, but in dynamic terms of resiliency, in other words, as "a resource for living". 1984 WHO revised the definition of health defined it as "the extent to which an individual or group is able to realize aspirations and satisfy needs and to change or cope with the environment. Health is a resource for everyday life, not the objective of living; it is a positive concept, emphasizing social and personal resources, as well as physical capacities".[10] Thus, health referred to the ability to maintain homeostasis and recover from insults. Mental, intellectual, emotional and social health referred to a person's ability to handle stress, to acquire skills, to maintain relationships, all of which form resources for resiliency and independent living.[9] This opens up many possibilities for health to be taught, strengthened and learned.
