There are several expressions to ask someone's age. That which I am most familiar with is “他几岁？”. However, I am informed that this can only be used for children (I think the problem is the 几， which implies a small number). How can I ask someone's age if they are an adult? Or perhaps asking how old someone was when something happened?
- How old is he (e.g. your father) now?
- How old was she when the accident happened?
- How old are you? (say, in the hospital, a nurse might ask a patient)
