Robert Booker's Mental Health VIPs

Mental calculation (also known as mental computation[1]) consists of arithmetical calculations made by the mind, within the brain, with no help from any supplies (such as pencil and paper) or devices such as a calculator. People may use mental calculation when computing tools are not available, when it is faster than other means of calculation (such as conventional educational institution methods), or even in a competitive context. Mental calculation often involves the use of specific techniques devised for specific types of problems. Many of these techniques take advantage of or rely on the decimal numeral system.

Health promotion is, as stated in the 1986 World Health Organization (WHO) Ottawa Charter for Health Promotion, the "process of enabling people to increase control over, and to improve their health."[1]

Scope

The WHO's 1986 Ottawa Charter for Health Promotion and then the 2005 Bangkok Charter for Health Promotion in a Globalized World defines health promotion as "the process of enabling people to increase control over their health and its determinants, and thereby improve their health".[2] Health promotion is a multifaceted approach that goes beyond individual behavior change. It encompasses a wide range of social and environmental interventions aimed at addressing health determinants such as income, housing, food security, employment, and quality working conditions.[3][4]

It is important to distinguish between health education and health promotion. Health education refers to structured learning activities aimed at improving health literacy, while health promotion encompasses broader social and environmental interventions designed to support healthy…
