Tom is right...
Tom is right about the different types. Type 1's get a bit annoyed at times, as they have people tell me, "Geez, it's too bad you didn't start excersizing sooner!" Type 1 is an auto-immune disorder where your body attacks the pancreas and ruins it's ability to create insulin. There is no 'real cure' yet other than a cell transplant, but then you're on anti rejection drugs forever - who wants to do that?
Type 2 people may become insulin dependent, but if they take steps early, they may be able to get away from it entirely.
