Amnesty for illegal workers is not just a slap in the face to black Americans. It's an economic disaster. I see illegal immigration and the adverse impact that it has on the political empowerment of African Americans, and the impact it has on the job market.
Also, when the body is in ketosis, one's breath may smell of acetone. This is due to the breakdown of acetoacetic acid into acetone and carbon dioxide which is exhaled through the lungs. Acetone is the chemical responsible for the smell of nail polish remover and some paint thinners.
Without trying to be too technical I think you can probably say that this ketone body smell is a consequence of fat metabolism. It depends on the nature of the smell. The smell of ketone bodies is characteristically sweet (somewhat like the smell of nail polish remover). It is different from an ammonia- like smell that might result from muscle (protein) breakdown. Ketone bodies are synthesized by the liver whenever fatty acid levels are high in the blood.
