Those serial smokers and unhealthy drinkers you know who you think are fine, are actually not. Well not in the long term at least. Their body is just building up the xenobiotics, heading towards multiple organ failures. Because organ failures typically take some time to become apparent, most people living unhealthy lifestyles barely become aware of the consequences of their choices until situations become dire. They’re walking around on a very fast countdown.
Making a conscious effort towards eating healthy is a great step to living a healthy life. You’re doing great, man.
