As a diabetic who was undiagnosed till it was way too late, I hope more people in Silicon Valley keep a close watch on their blood chemistry and look for clues that might indicate diabetes. 

Once discovered, you need to fight it constantly and it is a painful process. I have often fallen off the wagon, and struggle to get back on track, which I usually do, thanks to support from friends and family.
