It's long-term exposure to formaldehyde that is particularly dangerous. So I'm not surprised that there is no real evidence at this time.
It will take many years of observation before anything conclusive is known, one way or the other.
So should there be concern now? I actually don't know. That's above my pay grade. But the fact that there is no evidence now says nothing, either way.
And, that's my point. Did 60 Minutes SAY that? No, they lead us down a path where you could, if you didn't ask the obvious questions, come to only one conclusion.....you're going to die if you have this product in your home or office.
