Eat Dirt? After you

Robert Paterson's blog (which I discovered last week) has an interesting piece on new research into dirt, cleanliness, etc. .

Research is finally bearing out my own pet theory - that our immune system needs a challenge, just as our muscles and our minds do.

Many mammals eat dirt. I have seen many people in West and South Africa eat dirt. Why? Because it is good for us. Dirt, as in soil, is not just bad stuff nor is it dead.

Now I feel better that I only dusted the family room and Saturday, and got distracted before I finished all the living room. Better keep some of those good germs around.
