The phrase "poor lifestyle choices" refers to decisions or actions that can have negative consequences for a person's health, well-being and overall quality of life. These choices may involve habits such as poor diet, lack of exercise, excessive alcohol consumption, smoking, drug use, or other behaviors that can lead to physical illness, mental stress, or social problems. The phrase suggests that these choices are not in the best interest of an individual and could be improved upon with better decision-making skills and knowledge about healthy habits.
