"I went to the doctor and he said, 'You know those high blood-sugar numbers you've been dealing with since you were 36? Well, you've graduated! You've got Type 2 diabetes, young man.'"

Hanks said. "I said to her, 'Well, I'm going to have Type 2 diabetes, because there's no way I can weigh as much as I did in high school.'"

Hanks' high school weight: 96 pounds. "Most of it was that big, wide afro," Hanks said.

It affects about 24 million Americans and accounts for the more than 90 percent of diabetes cases diagnosed in the United States, according to the U.S. Food and Drug Administration.
