It seems that more and more people are thinking about health and starting to take real action that exercise is very important to do, not just about regulating diet. The past 3 years, this government program was still very quiet, not as enthusiastic as it is now. In the past, those who participated in car free day were people who really knew about health. The local government in my city also still closed half of the highway and vehicles could still pass through the city streets, but this year, car free day is 100 percent and no more vehicles are allowed to pass from 06.00 am to 08.00 am. And this car free day is only held on Sundays. Actually, it was a short time but it was more than enough.
