Hi CP, yes my W does like to keep busy nowadays. She has actually kept herself busy for the past 10 years or so, I would guess. What has changed is the nature of what she does. Things that she enjoyed doing 5 years ago, she no longer does.
You should encourage your H to get the kids involved in his projects. They're still young, but they can play where he is and stuff. When I was working on my garage, my 6 year old at the time joined me once and hammered nails into scrape wood.
