A pensioner is a person who receives a pension, which is a regular payment made to them after they retire from work. This payment is often based on their previous earnings and the number of years they contributed to a pension plan during their working life. Pensioners typically rely on these funds to support themselves financially in their retirement years. Pensions can come from various sources, including government programs, private companies, or personal savings plans. In many countries, such as the United States and United Kingdom, pensioners may also be eligible for additional benefits, like Social Security or state pensions, to help cover living expenses.
