What is is 27 considered old?

27 is generally not considered old, as most people at this age are still considered to be young adults. This is especially true in today's society, where people are living longer and pursuing higher education and career goals later in life. Therefore, 27 is often seen as the beginning of a person's prime years, where they have more experience and maturity than early adulthood, but are still able to enjoy the benefits of youth and good health.
