Yes. Religions are usually centered around fear and conformity. If you go your whole life believing in something as deep as the answer to life itself, it would probably be extremely traumatic to suddenly find out it's not true. I remember the day I decided I didn't believe in God anymore. It was honestly pretty scary. Fortunately, this happened when I was a teenager and I couldn't quite grasp the insanity of it all. I can't really imagine doing it as an adult. Not to mention the social repercussions.
