I still don't quite understand what is meant by dead and alive in relation to the flooring. I do understand what you mean, but I can't really comprehend it. People spend the whole day wearing clothes made from crude oil, eating their food out of Tupperware, brushing their teeth with plastic, working with computers made of plastic, but when it comes to flooring, it always has to be completely natural for the sake of - "Wohngesundheit". I appreciate wood very much, also as flooring, but I don't quite understand the argument of "dead and alive".
