My smelly friends! A girl was studying with me at the university, and it seemed to me that it smelled like corn from a bench. Nothing unpleasant, such a smell, you’ll think. But when her doctor was sitting next to her, she immediately wrote her directions to the endocrinologist, said that it was a typical smell of acetone and everyone broke out of the place to smell the same group... it went badly, but it was certain - diabetes was found.
