Agreed!
And this topic–like so many other topics–can be caused by a wide variety of factors. For example, I can smell the 5 Chinese elements within a person in that moment. Some people smell of certain diseases. (And this is not just a ACM thing. Ask veteran nurses. They’ll tell you of–say–the “cancer smell,” even in undiagnosed patients.)
To be clear, @Imresfreshed , I’m NOT suggesting that your brother might be ill or anything like that. I would have no idea about that. I am agreeing with the forum friends who, at the beginning of this thread, recommended that you determine the root cause of this symptom and that the “root cause” might be found in various places. The human body and the human condition is fascinatingly intricate and complex.
