Random information on the term “Blue”:

Azure (/ˈæʒər, ˈæz.jʊər/ AZH-ər, AZ-yoor) is a variation of blue that is often described as the color of the sky on a clear day.

On the RGB color wheel, “azure” (hexadecimal #007FFF) is defined as the color at 210 degrees, i.e., the hue halfway between blue and cyan. In the RGB color model, used to create all the colors on a television or computer screen, azure is created by adding a little green light to blue light. The complementary color of azure is orange.

In the X11 color system which became a standard for early web colors, azure is depicted as a pale cyan or white cyan.

The color azure ultimately takes its name from the intense blue mineral lapis lazuli. Lapis is the Latin word for “stone” and lāzulī is the genitive form of the Medieval Latin lāzulum, which is taken from the Arabic لازورد lāzaward, itself from the Persian لاژورد lāžaward, which is the name of the stone in Persian and also of a place where lapis lazuli was mined.

The name of the stone came to be associated with its color. The French azur, the Italian azzurro, the Polish lazur, Romanian azur and azuriu, the Portuguese and Spanish azul, Hungarian azúr, and the Catalan atzur, all come from the name and color of lapis lazuli.

Random information on the term “SAD”:

Sagittal abdominal diameter (SAD) is a measure of visceral obesity, the amount of fat in the gut region. SAD is the distance from the small of the back to the upper abdomen. SAD may be measured when standing or supine. SAD may be measured at any point from the narrowest point between the last rib and the iliac crests to the midpoint of the iliac crests.

SAD is a strong predictor of coronary disease, with higher values indicating increased risk independent of BMI.

For persons of normal BMI, SAD should be under 25 centimetres (9.8 in). The amount this measure exceeds 30 centimetres (12 in) correlates to increased cardiovascular risk and insulin resistance. SAD measure of men in their 40s, greater than 25 cm, also predicts significantly higher risk of Alzheimer’s disease 30 years later. An article in Annals of Neurology links visceral fat to lower brain volume.

A related measurement is Supine Abdominal Height (SAH), the abdominal height as measured in the supine position. The SAH method is easier for self-monitoring, but gives slightly lower results due to gravity; the values are not directly comparable.[citation needed]
