And, in typical 60 Minutes fashion, they didn't provide ONE shred of evidence of anyone getting sick because of it. It's right up there with THE "cell phones cause cancer" BS.
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.
