Healthy eating is the act of following a balanced nutritional diet. Because our ideas of what counts as "healthy" change, according to scientific advances in the field of nutrition, along with personal and cultural considerations, accepted standards of healthy eating differ from person to person, and throughout history.

Many governments and other organisations provide nutritional advice and launch schemes in order to promote healthy eating. Diets which lead to obesity (being severely overweight), diabetes, and other medical conditions, are a severe drain of resources for national health providers, and on businesses due to reduced productivity of staff.

A recent health campaign by the British government has attempted to impress the need to eat lots of fruit and vegetables using the slogan "5 a day". Adverts have given examples of what a portion of fruit or vegetables amounts to, and how 5 or more portions can be incorporated into one's diet.

Governments also put pressure on businesses to promote healthy food options, and regularly consider measures, such as banning the advertising of fast food, or taxing foods which are high in fat.

Music is the art of making sound by human voice or special instruments like violin, oboe, trumpet, drum and so on.

In music, sounds are arranged in time to give a pleasing result. There are many different kinds of music.

Music is written using note symbols on a staff, a series of horizontal lines. The pitch of the note depends on which line the note is on. The notes are separated into measures using vertical lines on the staff.
