Volunteering is generally considered an altruistic activity, intended to promote good or improve human quality of life. It is considered as serving the society through own interest, personal skills or learning, which in return produces a feeling of self-worth and respect, instead of money. Volunteering is also famous for the skill development, to socialize and to have fun. It is also intended to make contacts for possible employment or for a variety of other reasons.

Volunteering takes many forms, and can be performed by anyone with own set of skills. Many volunteers are specifically trained in the areas they work in, such as medicine, education, or emergency rescue. Other volunteers serve on an as-needed basis, such as in response to a natural disaster or for a beach-cleanup.

The verb Volunteer was first recorded in 1755, from the noun, in C.1600, "one who offers himself for military service," from M.Fr. Voluntaire. The word in the Non-military sense was first recorded during 1630s. The word Volunteering has a more recent usage, still predominantly military, coinciding with the word Community service.

The Honourable Usain St. Leo Bolt, OJ, C.D. ( /ˈjuːseɪn/; born 21 August 1986), is a Jamaican sprinter and a five-time World and three-time Olympic gold medalist. He is the world record and Olympic record holder in the 100 metres, the 200 metres and (along with his teammates) the 4×100 metres relay. He is the reigning Olympic champion in these three events, and is one of only seven athletes (along with Valerie Adams, Veronica Campbell-Brown, Jacques Freitag, Yelena Isinbayeva, Jana Pittman, Dani Samuels) to win world championships at the youth, junior, and senior level of an athletic event.

Bolt won a 200 m gold medal at the 2002 World Junior Championships, making him the competition's youngest-ever gold medalist at the time (since surpassed by Jacko Gill). In 2004, at the CARIFTA Games, he became the first junior sprinter to run the 200 m in less than 20 seconds with a time of 19.93 s, breaking the previous world junior record held by Roy Martin by two-tenths of a second. He turned professional in 2004, and although he competed at the 2004 Summer Olympics, he missed most of the next two seasons due to injuries. In 2007, he broke Don Quarrie's 200 m Jamaican record with a run of 19.75 s.
