I don't have a study, but an anecdote: for the last 18 months or so, I've worked 32 hours a week. Originally, I thought I would work 4x8, but as time went on, I really enjoy working 5 or 6 or 7 hours a day, depending on my desire and the work needing to be done. It's really nice to be able to not set an alarm and just wake up and work whenever you're ready or be able to take an afternoon off and take the kids to the park if you feel like it.
