This is good for a laugh! But id hardly call it a indepth study...id bet if you changed the study to social gathering (mothers meetings) you'd get similar results.
Plus it says religion as if the reader is supposed to know...so im guessing its alluding to westernised catholosism. Im a stark athiest, just incase you get the wrong idea, yet i find this artical/study beige in texture and pointless.
