I *swear* I found a discussion thread here a few years back about feeling overwhelmed by all the problems and natural disasters of the world and not being able to do more to help. Someone posted that there was research (or at least a theory) that our brains haven't evolved beyond "knowing" a set number of people - our local families and community members (essentially, people we'd met in person a few hundred years ago) vs. now being connected to people all over the world via the Internet (and extended news coverage of tragedies, etc.). Does this ring a bell for anyone?
