text: if there were less cars driving on the road then it could help alot of people. It could help people that are over wieght or obese because if they walked or jogged to the places they need to go then they could live a healthy life and they could lose wieght. and if people did this then there would be a whole lot of less pollution in the air. I think that if people walked instead of cars they would be happier and healthier.
