Nursing is a profession within the health care sector focused on the care of individuals, families, and communities so they may attain, maintain, or recover optimal health and quality of life.

Nurses may be differentiated from other health care providers by their approach to patient care, training, and scope of practice.

Nurses practice in many specialisms with differing levels of prescriber authority.

Many nurses provide care within the ordering scope of physicians, and this traditional role has shaped the public image of nurses as care providers.

However, nurses are permitted by most jurisdictions to practice independently in a variety of settings depending on training level.

In the postwar period, nurse education has undergone a process of diversification towards advanced and specialized credentials, and many of the traditional regulations and provider roles are changing.

A blog (a truncation of the expression weblog) is a discussion or informational website published on the World Wide Web consisting of discrete, often informal diary-style text entries ("posts").

Posts are typically displayed in reverse chronological order, so that the most recent post appears first, at the top of the web page.

Until 2009, blogs were usually the work of a single individual, occasionally of a small group, and often covered a single subject or topic.

In the 2010s, "multi-author blogs" (MABs) have developed, with posts written by large numbers of authors and sometimes professionally edited.

MABs from newspapers, other media outlets, universities, think tanks, advocacy groups, and similar institutions account for an increasing quantity of blog traffic.

The rise of Twitter and other "microblogging" systems helps integrate MABs and single-author blogs into the news media.

Blog can also be used as a verb, meaning to maintain or add content to a blog.

Education is the process of facilitating learning, or the acquisition of knowledge, skills, values, beliefs, and habits.

Educational methods include storytelling, discussion, teaching, training, and directed research.

Education frequently takes place under the guidance of educators, but learners may also educate themselves.

Education can take place in formal or informal settings and any experience that has a formative effect on the way one thinks, feels, or acts may be considered educational.

The methodology of teaching is called pedagogy.

The term lifestyle can denote the interests, opinions, behaviours, and behavioural orientations of an individual, group, or culture.
