We live in a causal world, so whatever you do now will have consequences. Not necessarily good or bad, but definitely real. According to WHO statistics, many factors affect such a unit as "health", and among these factors, the first place and a larger percentage is taken by the way of life. I'm not talking about abuse. Not about drugs and not about alcohol. In general, about the principles of your life: what you eat, how often you get medical examinations, how many medications you use, what chronic diseases you have and how to treat them, how long you walk, what kind of work you do, whether you have enough rest, etc. We are entering a new medical reality - in fact, we know how to treat most of the mass diseases, at least we understand the strategy, but the mortality of modern people is associated with our high life expectancy, we die from age-associated diseases. Diseases of mental breakdown come to the fore: Alzheimer's, the autistic spectrum and the like, which we do not know how to treat, we know how to create a kind of palliative-preventive environment. Heart attacks, strokes, oncology are also diseases of the age with their own exceptions (early strokes and pediatric oncology). And these diseases are directly related to the way of life. The more a person lives, the more the factors of his life affect his health. Don't let that young.
In my opinion it does. Health can be easily undermined with the help of drugs, akogol, gluttony, inactivity, and unwillingness to develop mentally. If in your youth you taught your body to endure prolonged physical and mental stress, this baggage will remain with you forever. In old age, he will not allow you to be a lying log, which will quickly rot from the diseases that have come, but will maintain motor and mental activity in you, prolong the period of a decent life in old age. The motto: "I will retire, I will not work" is for idiots, since such people very quickly join the "Alzheimer's Club" and become regulars at medical institutions - "work for a pharmacy".
