People come in all shapes and sizes. That's the way God makes us. How boring would it be if we all looked the same? Some things we can't change, like how tall we are or the color of our eyes. Some things we can, like how we treat other people or how we take care of our bodies. This book is about taking care of our bodies so they work the best they can. You'll find that life is a lot more fun when you have a body that works well.
