Parrster: These days I would be drawn to "Religion and philosophy" because I am learning that philosophy is not necessarily the ruminations of idle, disengaged dilettantes and that religion transcends a physical structure (church, synagogue, mosque, temple, etc.). Religion and philosophy can blend with daily life satisfactorily. Painful as the path may be, the unexamined life may not be worth living, as Socrates clearly pointed out (and even died for that belief). Far more is encompassed by religion and philosophy than I ever thought possible in my teens. :-)
In my 20s, I would have been drawn to "Travel and Places." I still love travel but I learn so much that stays with me long afterwards from religion and philosophy (for example, your hub, "Did God foresee this").
Great question! Kind regards, Stessily
