BBCnews has this story on a new kind of tatoo that would allow diabetics to continuously monitor their blood sugar levels. I've know several diabetics over the years, my grandmother lived with the disease for a very long time. I've always thought one of the real dangers was the inability to continuously monitor blood sugar. As far as I know, diabetes in and of itself isn't what causes all the trouble because it can be controlled. It's the loopy blood sugar extremes that cause the real damage. This could go a long, long way toward solving that problem.
