Several years ago I was having health problems. I was always coughing, my throat was raw, and I could hardly breath.
At one point, I asked my landlord to replace the carpet in my place (it had been there since I moved in, almost ten years).
When they came to remove the carpet, there were beautiful wood floors underneath. I told the landlord to skip the new carpet, and I'd keep the wood floors. He said no, because they were damaged and he didn't want to pay to have them sanded and polished.
I told him I didn't care and didn't want the carpet, and that he could do whatever he wants after I move. He agreed, and I got the wood floors.
In less than a week, my lungs were clear and I could breathe again.
It was the carpet that was making me sick!
