Interesting article on the benefits of having an older population: http://www.slate.com/articles/health_and_science/science_of_longevity/2013/09/evolution_and_social_consequences_of_old_age_infant_survival_and_elders.html
From the essay:
Old people are repositories of information, Caspari says. They know about the natural world, how to handle rare disasters, how to perform complicated skills, who is related to whom, where the food and caves and enemies are. They maintain and build intricate social networks. A lot of skills that allowed humans to take over the world take a lot of time and training to master, and they wouldn’t have been perfected or passed along without old people. “They can be great teachers,” Caspari says, “and they allow for more complex societies.” Old people made humans human.
And a bit that most regulars here can relate to:
Infanticide is a shocking crime today. And even though we allow parents to brainwash their children with fundamentalist home-schooling, when those parents choose religion over medical care, we quite rightly charge them with neglect, manslaughter, or—when it happens the second time—murder.
Live a good life... If there are no gods, then you will be gone, but will have lived a noble life that will live on in the memories of your loved ones. I am not afraid.
