I think most people drive around all day being vexed by images of mortality and vitality. All they're wondering about is how they're going to die and who they're going to sleep with, or variations on that theme - what job they're going to have, whether they're tall enough or skinny enough or smart or fast enough or make enough money, all of it plays into these two bookends.
Our culture is the first in a couple generations that attempts to have funerals with no bodies. We just disappear them. If you read the death notices in the paper today you'll notice that most of them are going to involve some type of memorial event, sans body, sans corpse. Also most likely without the gloomy stuff that comes with having a corpse in the room. But the way to deal with mortality is by dealing with the mortals. And you deal with death, big notion, by dealing with the dead thing.
We're very good when it comes to cats and dogs, we just don't have a clue when it comes to our people. We have them disappeared without any rubric or witnesses or anything like that. And then we plan these "celebrations of life", the operative words du jour. These celebrations are notable for the fact that everybody's welcome but the dead guy. This, to me, is offensive and I think perilous for our species. There is an intellectual - an artistic and moral - case that can be made for not only fruit and flowers in a bowl on a table but also a dead body in a box.
