Thanks for posting this Nielk - I have read Dr Shoemaker's work but have yet to convince my husband to - this short clip may do the job. I live in one of the wettest bits of the UK, and am contemplating some big life unheavals if mold is part of the equation for me. I want an objective correlate for my intuitions, and I suppose the Shoemaker tests may offer that partially. Has anyone here had his tests, and with what results?
