Interesting how it all comes back to the basics

I heard a rather startling statement on a health segment on the morning news - "Half of all breast cancer is preventable."  A pretty bold statement, but it was the method of prevention that caught my attention.  1. Exercise, 2.  Focus on a vegetable based diet (less meat).  3. Maintain a healthy weight.  4. Drink minimal amounts of alcohol.  It seems like every time disease prevention is discussed, it cones back to diet and exercise.  You'd think we'd get the message.
