The personal part is actually quite small. I spent a month working in a country where the host family did all my cleaning and cooking. All I had to do was eat, clean myself, and exercise. I felt I had a vast wealth of time. I was extremely productive yet had more leisure than normal. A stay at home spouse or a full time housekeeper is a vast multiplier. However, the former is rare/undesirable, and the latter costs a lot of money + introduces management complexity. Still, it's worth thinking cleanly about which part of chores actually require personal effort.
