I have a friend who is diabetic and I always feel so bad for her at how many different problems she has to deal with all the time. Like this one for example. She not only has to maintain her blood sugar levels, she has to really watch her dehydration levels as well.
She is kind of stubborn about not letting it get to her though. She runs marathons as a hobby! And has never had a problem, although the doctors warned her that hyperchloremia and other conditions could be an issue.
I think it's very inspirational, and shows other people that if you are careful about it, you really can do anything.
