While many diseases are contagious, diabetes is not a disease, remember?
Type 1 diabetes is caused by unknown reasons, but they are pretty sure association is not one of them. I mean, take my friends, THEY don't have diabetes. And if I was able to give diabetes to somone, I know some of MWMF that might enjoy trying it first hand...
I'll admit that I never had personal experience with this matter. I mean, I was diagnosed too late in life to have kids in my class taunt me by calling me "sugar girl" and run and hide as a result of their fear of catching diabetes.
So, while I don't think this myth is very widely believed anymore, I wanted to throw it out there. Unfortunately, I can't give away my diabetes. I can't even share it.
