That's absolutely true. I suggest also avoiding stress and anxiety. Sadly we see younger people enjoying all the bad habits, and when they get older, they fall sick and start to be treated by chemos, insulin, surgeries, etc.
Don't smoke cigarettes, they age your body horribly, including the skin. Don't drink alcohol to excess, it poisons the body. Don't eat so many carbs and sugar it causes diabetes, this accelerates deterioration of the circulatory system.
