What is this strange feeling?

I kept thinking something was different today. I was working around the house, refereeing the girls--since their favorite pasttime is fighting and wrestling and swinging at each other (where are the prim little girls I thought I had??)--just generally getting through a day at home. But I felt strange. It wasn't pain. It wasn't discomfort. It wasn't even bad.

But it was unfamiliar.

Let's see. I don't feel tired. I don't feel achy. I don't feel run down. Hmmmm...

Wait! Is this what healthy feels like? Is this what the body is supposed to do when it's fed proper food?

Well, whatta ya know...
