Oneker, FarNorth may be right. In fact, DH may be hoping you'll bring it up, so he can talk to you about it, while he still can. If you bring it up (gently, of course) and he brushes you off, then you'll know this isn't the case and can drop the subject till you see if he recovers. But if he seems relieved or eager to talk about it, that's a different story. He may feel the need to explain. Now that I've thought about it more I believe you should give him that chance. You may be glad you did.
If you had the chance to be the Roosevelt of our time what jobs would you provide?
The government changed women's pension age and called it progress. Did anyone actually ask you?
