### Yesterday I went to the doctor...

Yesterday I went to the doctor for my yearly physical. My blood pressure was high, my cholesterol was high, I'd gained some weight,and I didn't feel so hot.

My doctor said eating right doesn't have to be complicated and it would solve my physical problems. He said just think in colors; Fill your plate with bright colors; greens, yellows, reds, etc.

I went right home and ate an entire bowl of M&M's and sure enough, I felt better immediately. I never knew eating right could be so easy.
