Orthopedic cast
An orthopedic cast, body cast, plaster cast, or surgical cast, is a shell, frequently made from plaster or fiberglass, encasing a limb (or, in some cases, large portions of the body) to stabilize and hold anatomical structures, most often a broken bone (or bones), in place until healing is confirmed. It is similar in function to a splint.
Plaster bandages consist of a cotton bandage that has been combined with plaster of paris, which hardens after it has been made wet. Plaster of Paris is calcined gypsum (roasted gypsum), ground to a fine powder by milling. When water is added, the more soluble form of calcium sulfate returns to the relatively insoluble form, and heat is produced.
The setting of unmodified plaster starts about 10 minutes after mixing and is complete in about 45 minutes; however, the cast is not fully dry for 72 hours.
Nowadays bandages of synthetic materials are often used, often knitted fiberglass bandages impregnated with polyurethane, sometimes bandages of thermoplastic. These are lighter and dry much faster than plaster bandages. However, plaster can be more easily moulded to make a snug and therefore more comfortable fit. In addition, plaster is much smoother and does not snag clothing or abrade the skin.
Cast (gymnastics)
A cast is a basic skill on uneven bars in artistic gymnastics. From the front hang, a gymnast pikes (allowing the knee to touch the bar) and slides upwards to a handstand. Some gymnasts may perform the move with straddled legs. It is an "A" move in the Code of Points.

Fossil
Fossils (from Classical Latin fossilis; literally, "obtained by digging") are the preserved remains or traces of animals, plants, and other organisms from the remote past. The totality of fossils, both discovered and undiscovered, and their placement in fossiliferous (fossil-containing) rock formations and sedimentary layers (strata) is known as the fossil record.
The study of fossils across geological time, how they were formed, and the evolutionary relationships between taxa (phylogeny) are some of the most important functions of the science of paleontology. Such a preserved specimen is called a "fossil" if it is older than some minimum age, most often the arbitrary date of 10,000 years. Hence, fossils range in age from the youngest at the start of the Holocene Epoch to the oldest, chemical fossils from the Archaean Eon, up to 3.48 billion years old, or even older, 4.1 billion years old, according to a 2015 study. The observation that certain fossils were associated with certain rock strata led early geologists to recognize a geological timescale in the 19th century. The development of radiometric dating techniques in the early 20th century allowed geologists to determine the numerical or "absolute" age of the various strata and thereby the included fossils.

Promotion
On September 29, 2012, the band appeared on an episode of Red or Black?, appearing as part of a challenge involving using a handkerchief in their performance. They performed three songs in a medley, including the album's lead single "Loving the Sound". On December 9, 2012, they appeared as special guest performers in the final episode of the ninth series of The Xtra Factor. Despite not being a single from the album, "Runaround Sue" has been a staple of the band's live set since its inception and is one of the crowd favourites on tour. On October 4, 2012, Higher entered the Irish Albums Chart at #19, before entering the UK Albums Chart at #6 two days later, becoming the band's second top ten album in the UK.
