I just have a guest come in from Nigeria older than me. It is ok he is visiting and glad to have him. But he has a strong body odor. It is so strong that it takes over the room in few minutes after he comes in. I am not sure how to break the news to him, but something has to be done. Everone that comes in contact with him since he arrives pull me aside to say something about this. It is so hard to show him around the city in this condition. Please help any advise will be greatful.
