The Thumb is a region and a peninsula of Michigan, so named because the Lower Peninsula is shaped like a mitten; thus the Thumb is the area that looks like the thumb of the mitten. The Thumb is generally considered to be in the Mid-Michigan area of the state, located east of Flint/Tri-Cities region, and north of Southeast Michigan. The thumb is also branded as the Blue Water Area of Michigan.

The counties which constitute the Thumb are those forming the extended peninsula that stretches northward into Lake Huron and Saginaw Bay. There is no formal declaration for which of these counties are part of the Thumb. However, virtually all common definitions include Huron, Tuscola, and Sanilac counties. This definition is almost always extended to include Lapeer and St. Clair counties as well.

The Thumb region is very flat with fertile soil, the reason for its historical role as a chiefly agricultural area. Major agricultural products are sugar beets, navy beans,corn, fruits, and fish from the Saginaw Bay and Lake Huron. Few of the residents commute for work to Metropolitan Detroit or Flint or the Tri-Cities. Large cities in the Thumb area are Port Huron, Lapeer, Marysville, St. Clair, Sandusky, Bad Axe, and Caro. The majority of these cities are in the southern portion of the Thumb.

The thumb is the first digit of the hand. When a person is standing in the medical anatomical position (where the palm is facing anteriorly), the thumb is the lateral-most digit. The Medical Latin English noun for thumb is pollex (compare hallux for big toe), and the corresponding adjective for thumb is pollical.

The English word "finger" has two senses, even in the context of appendages of a single typical human hand:

Linguistically, it appears that the original sense was the broader of these two: penkwe-ros (also rendered as penqrós) was, in the inferred Proto-Indo-European language, a suffixed form of penkwe (or penqe), which has given rise to many Indo-European-family words (tens of them defined in English dictionaries) that involve or flow from concepts of fiveness.

The thumb shares the following with each of the other four fingers:

The thumb contrasts with each of the other four by being the only digit that:

and hence the etymology of the word: "tum" is Proto-Indo-European for " swelling " (cf "tumour" and "thigh") since the thumb is the stoutest of the digits.

John Leslie "Wes" Montgomery (March 6, 1923 – June 15, 1968) was an American jazz guitarist. He is widely considered one of the major jazz guitarists, emerging after such seminal figures as Django Reinhardt and Charlie Christian and influencing countless others, including Pat Martino, George Benson, Russell Malone, Emily Remler, Kenny Burrell, Pat Metheny, Steve Howe, and Jimi Hendrix.

Montgomery was born in Indianapolis, Indiana. According to NPR Jazz Profiles "The Life and Music Of Wes Montgomery," the nickname "Wes" was a child's abbreviation of his middle name, Leslie. He came from a musical family; his brothers, Monk (string bass and electric bass) and Buddy (vibraphone and piano), were jazz performers. The brothers released a number of albums together as the Montgomery Brothers. Although he was not skilled at reading music, he could learn complex melodies and riffs by ear. Montgomery started learning the six string guitar at the relatively late age of 20 by listening to and learning the recordings of his idol, guitarist Charlie Christian, however he had played a four string tenor guitar since age twelve. He was known for his ability to play Christian's solos note for note and was hired by Lionel Hampton for this ability.

Amy Jane Studt (born 22 March 1986) is an English singer, songwriter and musician. Growing up in a musical family she recorded her first demo by age 14, which eventually got her signed to Polydor. Studt released her first single "Just a Little Girl" in July 2002, to international success. It was followed almost a year later by "Misfit", which came to be her highest charting single. The same month her debut album False Smiles appeared. Late 2003 and early 2004 two more singles were released, "Under the Thumb" and "All I Wanna Do" respectively, but only to diminishing sales. That caused Polydor to drop Studt in February 2004.

From then until the end of 2006, Studt stayed out of the public eye. But in 2007 it was announced that she was working on a new album, now with the label 19 Entertainment. Some of her new material was published on MySpace. On 3 December 2007, "Furniture" was released as a digital single, and the album, My Paper Made Men, issued on 5 May 2008.

Studt was born in Hammersmith, London. Growing up in Bournemouth, Dorset, she started teaching herself piano, playing guitar and learning the oboe. Studt's father is a violinist and a conductor who has worked with Roy Orbison, Shirley Bassey and The Beatles to name a few, either touring or recording and has played on countless films, while her mother was head of music at St. Katherine's Primary school. Amy also studied a term at Vocaltech vocal school in London, working with close friend, fello co-writer and Vocaltech tutor Yak Bondy.
