The healthy living. Don't read it :)

Many of us sometimes think about our lives  and how we can improve quality and length of life (?). Sooner or later we are faced with the subject of a healthy lifestyle . Actually lifestyle is  the most important  factor in how long  your life will be. Not medicine or genetic predilection.There are  three things without which we  die very quickly. We eat, we drink, we .... ! Living is  impossible without it. We consume. I think if we provide prospective cohort research (??) on people who  follow healthy lifestyles we can understand why we forget about one thing lost . As a  rule it is people's  self-love. It is can to explain why they don't think about it.  A person who follow healthy living may drink only bottled water and eat only organic-grown food, but what you can say about pure air? Do you think about it? What do you do for it? Maybe you abandon your city? While time the most spread thoracic disease.( I don't understand this part)
