When people ask me this question, I usually say "nominal age", which may be a habit formed from childhood. After all, when I was a child, no matter what the circumstances, anyone asked me, I always reported my age for nothing, so I always remembered my age like this.

Later, I slowly found that the actual age was nearly 2 years younger than the nominal age. This is also a kind of psychological comfort. So if someone asks me this, I will naturally say it, but I don't think it will have much impact on myself, because even if I apply for a job myself, others will have their own judgment when they see my actual age.

So generally I don't care too much, because age is only secondary, and the most important thing is youth. Sometimes it allows us to continue to grow and learn. Gradually become more mature, because you will know more with more experience. Age is just a sign.
