I scanned some of the pages from your link.
It does look entertaining.
"Eighty-six percent of the fathers queried said they were ready "to take a paternity leave of several months to live their fatherhood more intensely," provided it caused "minimal financial impact.'"
Well no kidding. If I could take several months off and still get paid most of my salary I would take that deal in a second. I really doubt however, that these guys would be spending most of that time with their kids.
