I cannot tell you the number of times when I have thought that I have had low blood sugar, only to test and determine that I have high blood sugar. And over the years you can get so used to either high or low blood sugar that you don't even recognize it anymore. One of the things that they tell you on day 1 of being a diabetic is to not trust your feelings. Trust the glucose tester.

I am a type 1 diabetic and wear a sensor 24/7 that monitors my blood sugar. I realize that this is a specialized case, but for certain things the technology and need already exists and are being used.

Umm... what are you going to do once you pick up your rifle and try to take out the government that has gotten all uppity but also now has tanks rolling down the street at you. It was a fine idea when citizens had muskets and the army had muskets. But now the tables are not fair, and to get change you have to work from within.
