I completely agree with you that having kids is the best and patently designed for us way of achieving immortality, but I'd still love to talk to someone who grew up among the Ancient Greeks. Yes, people change with time, but some memories stay. I would be plain curious to find out which ones do. Reading (perhaps less so with watching recordings) doesn't quite give you that information, as evidenced by the fact that there are plenty of scholars out there who read a lot of material yet who utterly disagree with each other on what the Ancient Greeks (or Hebrews) were really like.
