Like it or not, people who went to prayer house or religious gatherings socialise more than people who stay indoor and only interact with limited amount of people. Assuming there's no fishy business going on with that particular chapter, they tend to be happier considering the fact human are social animal and the feeling of loneliness due to lack of human to human interaction is the build-in alarm system to warn us against solitude. It's this reason religion is so success because it's enforce togetherness and make you feels like you're part of something.

If we're going into a utopian world where human doesn't need to work anymore and social security is guaranteed, religious will be something even bigger than today.

Edit: forgot to mentioned, am atheist and give no shit to skyman, but somehow on the internet atheist can't have opinion that's not shitting on people with faith.
