The 4-Hour Body

The 4-Hour Body: An Uncommon Guide to Rapid Fat-Loss, Incredible Sex, and Becoming Superhuman (2010) is the second book by American writer Tim Ferriss.

Background

Ferriss's first book, and the one that made him famous, was The 4-Hour Workweek. Two facts informed his choice for his new book's topic: Firstly, he felt he did not want to write another book on business, as "I've said what I have to say about business. [...] I don't want to be 'The 4-Hour Workweek' guy; I'd prefer to be known for the way I approach the craft of writing and storytelling." Secondly, of the top ten Google searches bringing visitors to his weblog, four searches were some variation on "lose weight". That, as he put it, left him with "no Option B. [...] my next book was going to be The 4-Hour Body, or I wasn’t going to write another book."

Ferriss spent three years interviewing over 200 experts, ranging from doctors to athletes to black-market drug salesmen. He claims to have recorded every workout he had done since the age of 18, and from 2004 (three years before his first book was published) he had tracked a variety of blood chemistry measurements, including insulin levels, hemoglobin A1c, and free testosterone.

Early life

Ferriss grew up in East Hampton, New York and graduated from St. Paul's School in Concord, New Hampshire. He received a degree in East Asian Studies from Princeton University in 2000 (after switching from Neuroscience in an effort to "avoid putting printer jacks on cat heads"). After graduation, Ferriss worked in sales at a data storage company. Ferriss began building his own Internet business, BrainQUICKEN, while still employed at the company.

Chinese kickboxing

Ferriss has stated that, prior to his writing career, he won in the 165 lb. weight class at the 1999 USAWKF national Sanshou (Chinese kickboxing) championship through a process of shoving opponents out of the ring and by dramatically dehydrating himself before weigh in, and then rehydrating before the fight in order to compete several classes below his actual weight - a practice known as "Weight cutting".

Hour

The hour (common symbol: h or hr, h being the international form of the symbol) is a unit of measurement of time. In modern usage, an hour comprises 60 minutes, or 3,600 seconds. It is approximately ¹⁄₂₄ of a mean solar day.

An hour in the Universal Coordinated Time (UTC) time standard can include a negative or positive leap second, and may therefore have a duration of 3,599 or 3,601 seconds for adjustment purposes.

Although it is not a standard defined by the International System of Units, the hour is a unit accepted for use with SI, represented by the symbol h.

Etymology

The Middle English word ure first appears in the 13th century, as a loanword from Old French ure, ore, from Latin hōra.Hora, in turn, derives from Greek ὥρα ("season, time of day, hour"). In terms of the Proto-Indo-European language, ὥρα is a cognate of English year and is derived from the Proto-Indo-European word *i̯ēro- ("year, summer").

The ure of Middle English and the Anglo-French houre gradually supplanted the Old English nouns tīd (which survives in Modern English as tide) and stund. Stund is the progenitor of stound, which remains an archaic synonym for hour. Stund is related to the Old High German stunta (whence German Stunde, "hour, lesson"), from Germanic *stundō ("time, interval, while").

Silicon Valley

Silicon Valley is a nickname for the southern portion of the San Francisco Bay Area, which is located in part of the U.S. state of California known as Northern California. It is home to many of the world's largest high-tech corporations, as well as thousands of startup companies. Geographically, it encompasses all of the Santa Clara Valley, the southern half of the San Francisco Peninsula, and southern portions of the East Bay. It includes parts or most of Santa Clara County, San Mateo County, and Alameda County.

The word "valley" refers to the Santa Clara Valley, where the region has traditionally been centered, which includes the city of San Jose and surrounding cities and towns. The word "silicon" originally referred to the large number of silicon chip innovators and manufacturers in the region. The term "Silicon Valley" eventually came to refer to all high tech businesses in the area, and is now generally used as a synecdoche for the American high-technology economic sector. It also became a global synonym for leading high-tech research and enterprises, and thus inspired similar named locations, as well as research parks and technology centers with a comparable structure all around the world.
