Is this one of those incidentaloma things or are a lot of people actually living very toxic lives? When you did tests on 100 people's houses, were they surprised by the results enough to pay you for more data? There's enough fear around this kind of thing, but is there actually anything to fear once you look at the lay of the land of people's homes? (Similar to vitamin analogy... very few first worlders have vitamin deficiency, but there's entire vitamin aisles at the store)
