My Sincere Prayer for My Grandfather

Let us all pray for my sick grandpa who hardly breathes because his other lung is destroyed because of smoking, and now he regrets. He talked to my dad (also a smoker) to stop smoking, and to prevent getting sick like him, no much cure on it. Every time I see him, I pity him and think to myself that my dad should also stop. I hope that all smokers out there would read this story and would also STOP SMOKING...
