 You've noticed over the years, and I want to talk about what Bob has said, and it costs money. Over the years, home owners are talking about countertops, floors, tiles, glass, wine rooms. Okay, that's wonderful. That means people can afford class taste. However, we need to talk about family and the importance of having a healthy home. There is someone, a good friend of mine, his name is John, and we worked with him in New Orleans when we redid New Orleans. And his whole philosophy is that we can design a home with clean air quality that someone with asthma will lose it. In other words, over the years the asthma will go away if they live in a clean environment all the time, almost like a bubble. Do you agree? Absolutely. Tell me about this. So, you know, we talk about building high quality houses. As we look at changes to the energy code, one of the key things is building airtight houses. So, why do we build airtight? Well, first, you know, the perception is that we need to build airtight because that's what creates low energy houses. It reduces our energy bills. And so, you know, one of the best things I've ever heard is build it tight and then ventilate it right.
