I've seen a curious Chinese word 身体. At first, I have discovered that it means 'body' and is a word with a broader meaning in comparison to 身材 or 体格. But I never understood why it means 'body' or, yet another meaning, 'health'. There is a question 《 你身体好吗？》which literally means 'How is your health?'. While trying to seek for etymology, I turned out to be stuck because searching engines gave me no proper result about it.
Thanks for any help in finding the answer.
