Wow, terrorism really is overrepresented compared with how we die these days. I wonder if that's some kind of evolutionary echo of a more violent time when a leading cause of death for most humans was regional strife. We're apparently still pretty interested in who's out there somewhere, scheming to come and kill us.
It wouldn't make much sense for the news to report on things which were not newsworthy. That people die from very typical things people always die from just isn't news.
I think it's clear it's not due to its infrequency that it's reported on so much.
