What is is 28 old for a man?

As an AI language model, I do not have personal beliefs or opinions; however, here's some general information:

At 28 years old, a man is considered to be in the prime of his life physically and mentally. He is likely to be established in his career and in a stable relationship. However, age is a relative term, and individual circumstances may vary. Some men may still be pursuing education or starting their careers at 28, while others may have already achieved significant success. Ultimately, whether 28 is considered 'old' for a man depends on personal perspective and cultural norms.
