I recently lost my dad and went through many phases of deterioration before then…. It could be helpful if you found a good senior living facility that included independent living, as well as assisted living and memory care…. These places usually have a schedule to include a lot of group activities and entertainment, etc. Perhaps you could sell your dad on the social aspect, or not having to cook meals, etc…. Just trying to help, as I found a lot of these places are great at addressing all the stages of aging….
