Retirement age is the age at which a person is eligible to stop working and begin receiving retirement benefits, such as pensions or social security. This age can vary by country and is often influenced by factors like life expectancy and economic conditions. In many places, the typical retirement age is around 65 years. In some countries, individuals can choose to retire earlier or later than the official retirement age, which may affect the amount of benefits they receive. Early retirement may lead to reduced benefits, while working beyond the retirement age can increase them.
