text: With vehicles, we don't really have the need to walk or ride a bike anymore, because wherever we need to get to, we can just drive there. Excersise, to me, is really important. Walking, jogging, biking, ect. are good things to help keep things, such as our blood sugar in check. My uncle recently was having really high blood sugar levels and it was causing him to lose vision, and making him nausious. He went to the doctor about it and they informed him that it was so high because he doesn't get any excersise ot physical activities, he just sits on his couch all day, or when he needs to go somewhere, he drives. Medical issues like that could be prevented, especially if there was a limited car usage to where people would have to walk or bike to their destination.
