One in 12 Americans has diabetes. Among seniors, the disease affects about one in five people ages 65 to 74. Illinois Rep. Mike Tryon is one of those Americans with diabetes. He was diagnosed with the disease in 2006, shortly after he was elected to the Illinois House of Representatives. He’ll be a speaker at a special health policy academy planned for The Council of State Governments’ National Leadership Conference in La Quinta, Calif., from 8 a.m. to noon Friday, May 18. The academy will help legislators understand what role they can play in addressing the disease.
