How do I properly care for my independent older brother who likes his privacy?

I am bringing my elderly brother home to live with my husband and myself following a serious fall about two months ago (he has been in rehab/al facility since the fall) ... I am looking for ideas and suggestions that worked for you all out there who took care of your aging brother in your home! I took care of our mom in our home for 8 years, but I am thinking I need some good tips for caring for my older brother who has been totally independent all his life and likes his privacy .... just hoping somebody has cared for a much older brother who never married and lived a quiet, private life before now!
