People's lifestyles have changed, people are migrating to urban areas in large numbers, replacing clean fresh air with smoky gases, active physical activity is replaced by couches in front of the TV, and people who used to walk to their destinations now go by car. Also, as a result of the Second World War, it is believed that tobacco and alcohol became common drugs. In the past, people died mostly from infectious diseases, but now they mostly die from internal diseases. These are diseases caused by "wrong way of working". Avoiding bad habits, eating right, and moving, these 3 routines are the main strategies in the "fight against disease".
According to these, the key to a healthy, beautiful life and a long life is in our hands, and it is only a small effort of ours.
