I find it odd that people who subscribe to an atheistic worldview believe in something as mystical as luck. The cause of a situation has an actual cause not luck. I thought we lived in a cause-based universe not an "irrational" universe. To answer the medical gatekeeper question of why some people die at thirty and others live smoking at hundred? Good question yet it does have an answer. The cause is probably quality of prenatal/early life nutrition, biochemical individuality, and spiritual/mind factors, which were much higher quality a hundred years ago than thirty years ago (something the gatekeepers never differentiate between).
So yes there probably is a cause. Yet I'm accused of lacking in "critical thinking".
