When we have time for leisure, we usually need something that can amuse and entertain us. People who work indoors and spend most of their time sitting and doing sedentary office work can add physical activity to their lives by doing sports during their leisure time, such as playing a ball game, going camping, hiking or fishing. On the other hand, people whose jobs involve a lot of physical activity may prefer to spend their free time doing quiet, relaxing activities, such as reading books or magazines or watching TV. Some people find that collecting stamps, postcards, badges, model cars, planes or ships, bottles, or antiques are relaxing hobbies. Free time is organized in many schools and institutions. Schools may offer many extracurricular activities including hobby groups, sports activities, and choirs. Other institutions such as retirement homes and hospitals also offer activities such as clubs and meetings for playing games or simply organized periods for conversation. Most people like socializing with friends for dinner or a drink after a hard day at work. For many young people, having a regular night out a week is a normal part of their free time, whether it is joining friends for a drink in a pub, dining out in a restaurant, watching a film, playing video games or dancing at a club. Some people do leisure activities that also have a longer-term goal. In some cases, people do a leisure activity that they hope to turn into a full-time activity (e.g., volunteer paramedics who hope to eventually become professional paramedics). Many people also study part-time in evening university or college courses, both for the love of learning, and to help their career prospects.
