Define hobby and its types

Answer 1

A hobby is an activity or interest that is undertaken for pleasure or relaxation, often in one's spare time.The hobby of collecting consists of acquiring specific items based on a particular interest of the collector. These collections of things are often highly organized, carefully cataloged, and attractively displayed. Since collecting depends on the interests of the individual collector, it may deal with almost any subject. The depth and breadth of the collection may also vary. Some collectors choose to focus on a specific subtopic within their area of general interest: for example, 19th Century postage stamps, milk bottle labels from Sussex, or Mongolian harnesses and tack. Others prefer to keep a more general collection, accumulating Star Trek merchandise, or stamps from all countries of the world. There are also individuals, who take up collection of coins (Numismatics) or Autographs (Philography) as their hobby; in both the cases the people try to hold on to the identities. Some collections are capable of being completed, at least to the extent of owning one sample of each possible item in the collection (e.g. a copy of every book by Agatha Christie). Collectors who specifically try to assemble complete collections in this way are sometimes called "completists." Upon completing a particular collection, they may stop collecting, expand the collection to include related items, or begin an entirely new collection. The most popular fields in collecting have specialized commercial dealers that trade in the items being collected, as well as related accessories. Many of these dealers started as collectors themselves, then turned their hobby into a profession. There are some limitations on collecting, however. Someone who has the financial means to collect stamps might not be able to collect sports-cars, for example. One alternative to collecting physical objects is collecting experiences of a particular kind. Examples include collecting through observation or Photography (especially popular for transportation, e.g. train spotting, aircraft spotting, metrophiles, bus spotting; see also I-Spy), bird-watching, and systematically visiting continents, countries (and collecting stamps in their passports), states, national parks, counties etc.
