I have to say, that video has to have some of the most careful roughhousing I've ever seen. But I guess it is the New York Times.
My wife likes roughhousing with the kids more than I do, though my daughter loves using me as a jungle gym. I'm much more tolerant of the kids roughhousing with each other than my wife, though; I guess that comes from having been close in age to my brother, where we grew up fighting each other.
