Thankful Day #28

Thankful Day #28: I'm thankful for the germ theory. The gentleman pictured here, Louis Pasteur, helped to prove that little beings too small to see can make us sick. The germ theory replaced the miasma theory, that "bad air" caused contagious disease. Still, though, I think both should be taught in schools--it's JUST a theory!
