no i did not know this

that is so gross! It makes me want to get out the vacuum and dust my house again... I wonder how they measure these things..?

I found this link with Dust Bunny facts.. I thought you would enjoy this one too. :) http://www.dustbunnies.com/dust_bunny_facts.htm - DNatureofDTrain
