Most people in the morning don't have time to just walk around the countryside or housing. There are many factors that become a barrier, mostly because they are busy with activities to get to work and partly because they have not woken up.
In my area, the awareness of people to take the time in the morning to walk is very lacking, even though these activities are very good for maintaining health. Morning is a perfect time to walk because the air is still fresh and free of pollution.
