I retired back in 2000. Lots of time to figure out the rules. My wife is a nurse and hospice care giver and I do a lot of volunteer work. That keeps her very busy so we both have many interests. We have a full basement divided into her sewing area and my workshop. I have a home office in a former bedroom and work space in the garage. She manages projects in the house, I manage the outside. You need to find ways to support each other and not get in each others way.
