I never cease to be astounded by things of a high-tech nature. I don't really know how we ever existed without things like MRI, cruise control, and Wii. Now, I have stumbled across yet another miracle of modern tech. While digging through the cabinets for something totally unrelated, I found one of those little digital gadgets that people use to check their blood sugar. Well, ever the scientist, I just HAD to find out what it would say if someone used it that was NOT diabetic or anything. So I painfully poked my finger with the little finger poker and smeared a rather disturbing amount of blood on the little blood smear thingie and waited. After a minute or two the display went black and then read "Your finger hurts". How the hell did it know?
