Asceticism (from the Greek: ἄσκησις, áskēsis, "exercise" or "training") describes a lifestyle characterized by abstinence from various worldly pleasures, often with the aim of pursuing religious and spiritual goals. Many religious traditions (e.g. Buddhism, Jainism, the Christian desert fathers) include practices that involve restraint with respect to actions of body, speech, and mind. The founders and earliest practitioners of these religions lived extremely austere lifestyles, refraining from sensual pleasures and the accumulation of material wealth. They practiced asceticism not as a rejection of the enjoyment of life, or because the practices themselves are virtuous, but as an aid in the pursuit of salvation or liberation.

The adjective "ascetic" derives from the ancient Greek term askēsis, which means training or exercise. The original usage did not refer to self-denial, but to the physical training required for athletic events. Its usage later extended to practices that are used in all major religious traditions, in varying degrees.

Sidney K. "Sid" Meier (born February 24, 1954) is a Canadian-American programmer and designer of several popular strategy video games and simulation video games, most notably Civilization. Meier co-founded MicroProse in 1982 and is a Director of Creative Development for computer game developer Firaxis Games, which he co-founded with Jeff Briggs and Brian Reynolds in 1996. He has won several prestigious accolades for his contributions to the computer games industry.

Sid Meier was born in Sarnia, Ontario, Canada. He graduated from the University of Michigan.

Meier founded MicroProse together with Bill Stealey in 1982. MicroProse initially developed flight simulator video games, such as Silent Service and F-19 Stealth Fighter. In 1987, the company released Sid Meier's Pirates!, which also began a trend of placing Meier's name in the titles of his games. Meier later explained that the inclusion of his name was because of the dramatic departure in the design of Pirates! compared to the company's earlier games. Stealey decided that it would improve the company's branding, believing that it would make those who purchased the flight simulators more likely to play Pirates!. After the release of F-19 Stealth Fighter, Meier decided to focus on developing strategy games. He later said, "Everything I thought was cool about a flight simulator had gone into that game." Inspired by SimCity and Empire!, Meier created Railroad Tycoon and later the game series for which he is most widely recognized, Civilization, although he designed only the first installment. Meier eventually left MicroProse and in 1996 founded Firaxis Games along with veteran designer and gaming executive Jeff Briggs. Today Firaxis makes strategy games, many of which are follow-ups to Meier titles, such as Civilization V and Pirates!. In 1996 he was awarded US Patent 5,496,962 for a "System for Real-Time Music Composition and Synthesis" used in a product called "CPU Bach".
