Interesting question...and the answer is probably not a surprise.
Your body talks to you all the time. I know mine does. It tells me when it has had enough...and it tells me when it has not had enough.
These days it is saying it needs less body and more exercise. Not for any other reason than those two things will make it easier to navigate the world.
I love the saying that your body is the place where your spirit lives...so give it a fabulous home to hang out. :)
Something I am focusing on for 2013. What's your body saying to you this morning?
