 And so definitely the cell phone is a big part of that change in posture as well because everything in our body remodels according to use. So that's why when you exercise, you get stronger. It's why when you're getting adjusted, your body learns a new position because your body responds to what you give it. And not just to use, but you give it bad food, you get less healthy. Whatever you give it, it's going to do it. So if you're giving it just bad posture by looking down at a phone all the time, your posture is going to get bad. Mm-hmm.
