What is what age is senior citizen?

The age at which someone is considered a senior citizen can vary depending on the context. Generally, age 65 is widely considered the beginning of senior citizenship. This age is often associated with retirement and eligibility for government programs like Social Security and Medicare in the United States. However, some businesses and organizations may offer senior discounts or benefits starting at age 50 or 55. There isn't a single, universally agreed-upon age.
