The 20th century is considered the most violent century in terms of sheer number. Death rates are a weird thing to think about in per capita terms. If you look at it that way, then an individual life is worth less now than it used to be. Whether your death is a 1 millionth or 1 billionth of the population makes no difference to your family and friends.

There still 90 years left in this century. Judging by previous ones, a lot of awesome and terrible things are going to happen. Technology amplifies man's capacity for creation and destruction. Speaking as a 25 year old, I'm optimistic that life will continue to be an interesting ride.
