Brain vs. Body

All right, I've decided my brain and body are fighting.  I know this, because every time my brain wakes up and says I need to keep the body healthy, the body gets ill or hurts.  This can be if I plan for a week in the future, a day in the future, a weekend in the future, or the new year.  Could it be that the body is telling the brain to shut up? 

Brain:  Body you need to get back on the diabetes band wagon.  The reason you are feeling so tired and headachy is because you are eating horribly.

Body:  Shut up brain.  I'm sick.......feed me carbs.

Brain:  Body you need to start exercising.  We'll feel better about ourselves, conquer the winter blues, lower our blood pressure and cholesteral, and sleep better.

Body:  Shut up brain.  I'm sick.....we need to lay around and watch more TV. ---or--- Shut up brain, I'll make you hurt so bad you can't get out of bed other than to take more pain killers.

I think I need to invite a third body part to come in and mediate.
