I was raised in a religious Jewish family and attended synagogue on Friday night and Saturday morning, plus Hebrew school Sunday morning and Tuesday afternoon. So I was there more days than I wasn't. I became an atheist at 14 and eventually stopped going.
Since then I have attended Christian, Muslim, and Native American ceremonies. I haven't attended any kind of religious services for around a decade. I find religion interesting as an academic subject, and have read the Bible, the Quran, the Tao Te Ching, and many commentaries and analysts, but have no interest in participating in any religious community or worship other than as an observer.
