Absent imminent death or curtailed brain function, it really doesn't matter that much whether presidential candidates have a long list of chronic illnesses. I'm 44 and I'm ready for a stool to sit on after about 15 minutes these days. I suppose the question of appropriate transparency is open to debate, but who cares? As far as I can tell, everyone over 50 in this country (or younger) has some sort of chronic something and is drugged to the gills because of it. I'm somewhat kidding, and not at all knocking people who have medical conditions. The opposite, in fact! I'm trying to point out that it's pretty normal, if not quite universal.
Kinda funny that it's about all they've got.
