Michael McBrayer of St. Paul, Minn., needs to pay a lot attention to his health.
"I give myself shots multiple times a day, as well as controlling my diet and exercise," he says.
Ten years ago, McBrayer learned he has Type 1 diabetes. Now he knows he faces dire consequences if he fails to control his blood sugar.
"Kidney failure, blindness, heart disease — all those things are looming out there," he says.
