I personally don't see any issue with waiting till you are 50 to raise children, today... even when the life expectancy is 75. Life is to be celebrated no matter what age someone is when they become parents. If biology were no constraint, I can imagine some people would have children once every hundred years, and spend the next century shepherding them into good position in their growing dynasty. That said, with vastly increased life spans, the whole notion of reproduction and marriage would take on new meaning, and I doubt many of the ideas we ascribe to today will be of much concern in the future. > Yeah, I know. It's all hypothetical for us Yes, which is why I don't see much of a reason to be so pessimistic. Those whom want to live forever---hypothetically will. Those who do not, as they are bored or tired, will choose not to continue onwards. I can imagine a future of mostly happy immortals.
