The real reason people attend church?

An interesting article here indicates that "a majority of participants" release oxytocin (a hormone also released during orgasm and breastfeeding, incidentally) during rituals, religious or otherwise. This may help explain why people enjoy going to church on Sunday, and why churchgoers are "happier and healthier" in many surveys. Then again, one study doesn't really tell us much of anything and should probably be taken with several grains of salt.
