<bot>: Smoking is one of the most harmful activities you can do for your health, as it increases your risk of heart disease, stroke, lung cancer, and many other serious illnesses. It also decreases your sense of taste and smell, which can lead to an increased risk of malnutrition. Additionally, smoking can cause premature aging, tooth decay, and poor wound healing.
