I understand Sotomayor has some health issues that could move her retirement or passing up years. I see her as less bad than Kagan or Ginsburg, but plenty bad enough.
I never go by the age thing. Years ago an opponent of Strom Thurmond focused throughout his campaign on Thurmond’s advanced age vs the opponent who was only 48 at the time (IIRC). The opponent died before the end of the term being contested and ole Strom lived on another few decades.
From what I remember, she is a Type 2 diabetic. Depending on how adherent she is to her treatment and dietary requirements, will determine how long she remains ‘healthy’. I use the quotation marks due to the fact diabetes is sometimes a very difficult disease to manage. Other health issues arise from being diabetic. With her age and apparent weight, I would say she is not doing a great job managing things. Failure to manage her disease will result in a greatly shortened life. Not wishing ill, just stating facts.
