Thefotochef - You are not whom I was referring to when I said it was a stupid question. Kindly reread my post you quoted. The 'stupiest question, never used a glucose meter' comment was directed at the poster that asked if I had a link referencing that ebook readers cannot be used as a glucose reader. Not you. If that person had ever used a glucose meter, they'd know there is no way a digital book reader could ever measure blood glucose.
My father had both of his legs chopped off above his knees because of diabetes. I slept on the floor of a hospital for two months until he was moved to ICU & died because of it. I am pre-diabetic so I need to measure my blood sugars. So while yes we all should think before speaking, I pose to you to learn how to comprehend what you read before you comment.
