I'm being insouciant, as is the author of the article, up to a point, but enjoy this quote:
A vast body of research, amassed over recent decades, shows that religious belief is physically and psychologically beneficial – to a remarkable degree.
In 2004, scholars at UCLA revealed that college students involved in religious activities are likely to have better mental health. In 2006, population researchers at the University of Texas discovered that the more often you go to church, the longer you live. In the same year researchers at Duke University in America discovered that religious people have stronger immune systems than the irreligious. They also established that churchgoers have lower blood pressure.
Meanwhile in 2009 a team of Harvard psychologists discovered that believers who checked into hospital with broken hips reported less depression, had shorter hospital stays, and could hobble further when they left hospital – as compared to their similarly crippled but heathen fellow-sufferers.
The list goes on. In the last few years scientists have revealed that believers, compared to non-believers, have better outcomes from breast cancer, coronary disease, mental illness, Aids, and rheumatoid arthritis. Believers even get better results from IVF. Likewise, believers also report greater levels of happiness, are less likely to commit suicide, and cope with stressful events much better. Believers also have more kids.
