Smoking after 40 creates a dangerous problem: it damages brain blood vessels and increases free radicals, leading to dementia and cognitive decline. The solution is to quit now using tools like Cognitive Behavioural Therapy (CBT), specialized books, or motivational podcasts to break the mental addiction. The benefit is immediate: within weeks, lung and heart health improve, and memory begins to recover, proving itโs never too late to reclaim a sharper, healthier mind.
