The data that matters to me is the data I receive after I’ve finished eating something. Do I feel good after eating a roast chicken with gravy and mashed potatoes and a pile of shaved sautéed Brussels sprouts? Yes. How about after I eat a bag of Cheetos? Not so good. What does that mean? Think about it. Think. Do you feel good after you exercise? Yes, because it’s good for you. Or you can hunt for data on the Internets if you want The Truth. Go ahead, read up on it. Or watch all the “a new study finds” stories on the ABC Nightly News.
