I was always annoyed by this question for the same reasoning. However, as another person already said, you can sometimes feel it in some part of the body. When feeling bad, it feels like pressure in my stomach, there a a few other.such connections. Now I find it somewhat useful as part of mindfullness.

I do still get annoyed when asked this question, partly because whenever he asks the question i do not feel it anywhere, also it seems irrelevant. But the main reason is probably defiance that this seemingly stupid question of him was sensible all along. So much I had to write this response.
