When you identify with the body, you take on all the concerns of the body. 
When the body has a flu, you have a flu. When the body is tired, you are tired. 
You are taking on unnecessary burdens that belong to the body and not to you. 

Trust the body. 
If it knows how to navigate its way from the embryo to the baby form, if it knows how to navigate its way through the birth canal, then surely it has proven to you that it knows how to navigate other (less complex) situations.
