From constipation, you will attract multiple diseases. Your body will become a skeletal frame. U will face many types of deaths. U will reach an Intensive Care Unit of a living hell on earth i.e., hospital or a nursing home. Quit smoking, maintain health and be happy, if you do not want to expect the above. If at all you want to die, die healthy and peacefully.
