For me it was just a realisation that reproduction is just one way we pass ourselves on, but one that has a lot of evolutionary push to make us want to do. For me, I was just born without that push for whatever reason. I'm not sure if it's a symptom of undiagnosed asperger's that I suspect or some other thing like that. Regardless of the reasons why I don't possess that drive, I don't think children are the only way we pass on. In fact I think every action we do is a form of reproduction, including building stone walls. Maybe people think that there is something inherently different between biologically producing a living being and other forms of interacting with the world but I don't believe so personally. In terms of your moment in your 20s, the way I see it is that it goes beyond my conventional existence as a human: I'm not just the product of all my direct ancestors, but also of all the causes and effects which have effected those ancestors. It's obvious that I am the continuation of my great great great grandfather, however I am also the continuation of my great great great grandfathers lunch that fed him, or doctor that saved him, or the Sun that supported him. Reproduction is an essential component for continued existence of sentient beings, but so is food, so is warmth, so is water. I feel that the Sun is just as much my parent as my biological parents.
