Thirst

Thirst is the craving for fluids, resulting in the basic instinct of animals to drink. It is an essential mechanism involved in fluid balance. It arises from a lack of fluids or an increase in the concentration of certain osmolites, such as salt. If the water volume of the body falls below a certain threshold or the osmolite concentration becomes too high, the brain signals thirst.

Continuous dehydration can cause many problems, but is most often associated with renal problems and neurological problems such as seizures. Excessive thirst, known as polydipsia, along with excessive urination, known as polyuria, may be an indication of diabetes mellitus or diabetes insipidus.

There are receptors and other systems in the body that detect a decreased volume or an increased osmolite concentration. They signal to the central nervous system, where central processing succeeds. Some sources, therefore, distinguish "extracellular thirst" from "intracellular thirst", where extracellular thirst is thirst generated by decreased volume and intracellular thirst is thirst generated by increased osmolite concentration. Nevertheless, the craving itself is something generated from central processing in the brain, no matter how it is detected.

The Thirst

The Thirst are an English indie rock band based in Brixton, London. The band consists of brothers Mensah (vocals/guitar) and Kwame Hart (bass), Mark Lenihan (guitar) and Marcus Harris (drums/backing vocals).

History

Mensah received an electric guitar from his parents around the age of 14, and after a few years he decided to get his brother, Kwame, a bass guitar, buying it from 'cash converters'. This inspired friends Mark and Marcus to complete the band by purchasing a second guitar and drum kit respectively. The main inspiration behind starting the band was their strong musical upbringing and appreciation as well as the need to stay away from the life of street crime in London. "I [Mensah] started playing now and again and got these three round just smoking and trying to stay off the road. My mum allowed us all to come round her house and chill out. She’d rather that than us hanging on the corner smoking weed." Their musical influences include Jimi Hendrix, punk, drum n bass, and local hip-hop.

Brian May

Brian Harold May, CBE (born 19 July 1947) is an English musician, singer, songwriter and astrophysicist, best known as the lead guitarist of the rock band Queen. He uses a home-built electric guitar, called the Red Special. His compositions for the band include "We Will Rock You", "Tie Your Mother Down", "I Want It All", "Fat Bottomed Girls", "The Prophet's Song", "Flash", "Hammer to Fall", "Save Me", "Who Wants to Live Forever" and "The Show Must Go On".

May was a co-founder of Queen with lead singer Freddie Mercury and drummer Roger Taylor, having previously performed with Taylor in the band Smile, which he had joined while he was at university. Within five years of their formation in 1970 and the recruitment of bass player John Deacon completing the lineup, Queen had become established as one of the biggest rock bands in Britain with the album A Night at the Opera and its single "Bohemian Rhapsody". From the mid-1970s until the early 1990s, Queen were an almost constant presence in the UK charts and played some of the biggest venues in the world, most notably giving an acclaimed performance at Live Aid in 1985. As a member of Queen, May became regarded as a virtuoso musician and he was identified with a distinctive sound created through his layered guitar work. Following the death of Mercury in 1991, Queen were put on hiatus for several years but were eventually reconvened by May and Taylor for further performances featuring other vocalists. In 2005, a Planet Rock poll saw May voted the 7th greatest guitarist of all time. He was ranked at No. 26 on Rolling Stone magazine's list of the "100 Greatest Guitarists of All Time". In 2012, May was ranked the 2nd greatest guitarist of all time by a Guitar World magazine readers poll.
