Type 1 Diabetes and Life Expectancy

It's probably because I have type 1 diabetes myself, but the fact that Sonia Sotomayor having it has been raised as a concern irks me. By all accounts she manages her condition quite well. Even if she has a life seven to ten years shorter than average, she is only 54 and should put in a lot of decent years on the bench. This is not even close to being a valid reason to question her ability to serve on the Supreme Court. Of course, other attacks on her have been much worse.
