It’s not about your death. It’s about the lives of your grandchildren and their grandchildren.
And much more important the lives of those that showed up at the funeral or memorial service (or should have.) For most people only the children and grandchildren have any real interaction with the live parent. After that the genetic and memetic legacy is important in the progeny, but the folks at the funeral carry most of the social and loving legacy of the deceased. This is a fact for all, religious or not. Christians may get pie in the sky after they die, and Muslims their attendants, but that is myth. Those at the funeral are truth, whether they are there or not."
