Volunteering is defined as unpaid work done willingly to benefit others or society as a whole. It involves committing time and energy through a non-profit organization for causes like education, sports, culture, or the environment. Over 100 million Europeans volunteer their time, most commonly in sports, education, arts, or cultural activities. Volunteering can take various forms in terms of topic, time commitment, location, presence, targeted age groups, and whether it's done individually or as part of a team.
