Tom Hanks is looking slimmer these days, and when David Letterman asked him about his weight last night on the Late Show, Hanks offered a surprising revelation: He has type 2 diabetes, the Huffington Post reports. He's been struggling with high blood sugar since age 36, Hanks said, and his doctor recently told him, "You've graduated. You've got type 2 diabetes, young man." Hanks didn't seem all that bothered by the news: "My doctor said, ‘Look, if you can weigh as much as you weighed in high school, you will essentially be completely healthy and will not have type 2 diabetes,'" he said. "And I said to her, 'Well, I’m gonna have type 2 diabetes.'"
