On second thought, "very unrealistic" was harsh. I (or anyone) could nitpick a few hours per week here and there but nothing significant. You are right that it's really just about current life situation. As a married homeowner, my responsibility time is much higher, hah.

No kidding! I feel like my wife & I get somewhere between 1-2hr/day of discretionary time, and it's not in large blocks most days... and it includes things like calling the utility provider to figure out a billing problem, vacation & event planning, chatting with neighbors/friends, and anything else that isn't a natural part of the "committed parent + homeowner" categories.
