weekly jounal9: activity

I read an article of Science Daily “19-year-olds as sedentary as 60-year-olds, study suggests”, June 15, 2017. The article said that physical activity among children is declining and it is comparable to that of the age of 60.  The World Health Organization (WHO)  confirmed the moderates physical activity a day is 60 minutes a day at least. However, more than 75 percent girls and 50 percent boys do not have physical activity time recommended by WHO. To solve this problem in the article, we should reduce sedentary behavior and increase ow-intensity levels of physical activity. I find that taking the stairs is good example.
