I'm in the same boat as you and @bclane. Hubby seems to remember everything about his childhood, which he talks about incessantly, but can't remember whether he just ate. He has trouble implementing anything involving planning, so appointments, bookkeeping, etc are all left up to me. I am 'directionally impaired' (get lost easily - thank goodness for Google Maps), and he used to have an uncanny sense of direction, but that is gone and he would get lost a mile from here. He used to be very handy, but now simple 'Honey-do' jobs go undone. I think his hearing is normal, but he 'misunderstands' what I've said, so sometimes he gets mad at me thinking I said something different. I too find myself raising my voice impatiently when he asks me to repeat what I just said. He wants to use his smart phone but it is frustrating trying to show him over and over how to operate it. I too read constantly - only using audiobooks, so I can 'read' even when walking or doing chores. They truly do take one's mind off the tedium of daily life.
We're not planning very well for the future - I guess we'll just have to handle what comes when it comes. Fortunately I have a wonderful son who will help us, even though he lives far away.
