Scientist attribute the phenomenon to the infamous “cuddle hormone”, Oxtocin, which pours into the bloodstream during orgasm and heightens ecstasy and a religious reaction.
Oxytocin is said to also evoke other emotions such as awe, gratitude, hope, inspiration, love, and serenity.
How much Oxytocin you get is geared to the presence of the gene CD38, which regulates the hormone’s release in the brain.
Apparently Atheists don't have the gene and are therefore doomed to a short life of disrespect, despair, ingratitude, animosity, anxiety, and a lack of nooky.
