 Well, you get a lot of joint pain, sinus headaches. You get a lot of things that you respond to, the body responds to. All you got to do is eliminate it, and the body goes right back to normal. But especially the older folks, I mean, we had a situation in my house. We had some mold growing, and my wife said, I don't know what happened and why it did it. I have ideas. And I was getting these pains in my hands, these joint pains, and I thought I was eating too many carbs, but it was the mold.
