Absolutely. However, lately I've been going at humdrum daily stuff at a pace so slowly it's just a tad shy of ridiculous. Things like making coffee, walking the dogs, vacuuming, driving (not obstructing anyone, just a relaxed pace) and also cooking. I've found very little downside; if you relax while you're doing your dailies you don't need to rush through so you can plop down on the couch.

I don't have children though, not sure how that factors in.
