When we think of the words "most clean-living," we often imagine someone who is healthy, disciplined, and responsible. However, there are plenty of antonyms that describe people who do not embody these qualities. Some antonyms could be "sloppy," "careless," "undisciplined," "unhealthy," "reckless," or "negligent." These words describe people who do not prioritize their physical or mental health, or who lack self-control and responsibility. While it's important to strive to be clean-living, it's also important to recognize and understand the opposite qualities so that we can avoid them and focus on making positive choices.
