I found this book to be an easy read with a ton of practical information about dealing with mold. It is especially helpful in explaining the different types of mold, how they effect some people and how to safely remove it. Some people are lucky enough not to feel the effects of mold on their body, others do. For those that do, this book is really helpful. For those that don't, but have a loved one that does, this book could be helpful in understanding the big picture. I never in a million years thought I was mold sensitive. While dealing with medical issues my practitioner suggested that I get tested to see if I had mold toxicity and sure enough I did. As we started the remediation process and I was exposed to less things that were contaminated with mold I was shocked at how much better I felt. If your partner is telling you that it is effecting them, please know that just because you can not see it doesn't meant that it isn't there.
