things to keep your spouse with early Alzheimer's busy

Can anyone share some ideas about what you do to keep your spouse with early Alzheimer's busy during the day. My husband is a golfer. He still golfs occasionally, but not nearly as much as he used to. Most days he is home here with me and just doesn't know what to do with himself. He constantly asks, "what are we doing today?" and expects me to entertain him. He runs errands with me, which he never did before and follows me around the house like a shadow. I have plenty to do around the house but he is not one who likes to help with housework. I still work part time and when I am gone all he does is watch tv. I feel guilty at work because I know he doesn't have anything to do, but I need to work to keep my sanity. When I read that I am supposed to give him towels to fold, or silverware to sort, that doesn't make sense at this stage. He is capable of doing lots of things but does not have the motivation to develop a new hobby. I have tried to get him to play games or do puzzles, but that is not his thing. Thanks for any suggestions, because I am out of ideas.
