This is a hot deal for EVERYONE. T1&T2 rates are rising dramatically, especially among people with no family history of diabetes or thyroid problems. Chances are, if you don't know someone with it, you might soon. It might also help to recognize symptoms early.
I was diagnosed with T1 when I was in high school. Few people really know much unless they have a friend or relative with it. Education saves (or prolongs) lives.
Edit: just realized this is one of those "chicken soup" books...I'd guess it's probably filled with stories about "overcoming" the difficulties of diabetes and other relatively useless smarmy stuff. Links for people who want real info:
American diabetes assoc.
Diabetes.com at webMD
Diabetes info from the CDC
also, for anyone with Type I, I highly recomend disetronic insulin pumps. pumps make precise managemnet much easier and I got over the inconviences very quickly.
