Is 21 too old for chess?

I understand that chess is a game that can be enjoyed by people of all ages, but I'm curious to know what your thoughts are on the matter of age and chess. Specifically, I'm wondering if you believe that 21 is too old to start playing chess? Could you elaborate on your reasoning, taking into consideration factors such as the mental and strategic benefits of the game, as well as the potential social aspects of joining a chess club or community? I'm interested in hearing your perspective on this topic.
