Flee bad habits, my plea

Though warned to stop smoking and drinking beer, Why should I quit things that give me such joy? So much wise advice I refused to hear. All good things of life I vowed to enjoy. But when I was told I had lung cancer, And my liver scarred with cirrhosis. Without the doctor giving the answer, To my question, I guessed the prognosis. I'm tied to survival with a thin thread, My vibrant past now fades like a mirage, Instead, imminent death is what I dread. My life wracked with pains, no balm to assuage. I finally constructed my life a mess, Chaos now lives deep inside my body, Causing my heart a serious distress. Flee bad habits, my plea to somebody.
