hamster-bamster, you have misunderstood completely. What makes incest a taboo is NOT that people have known each other all their lives and lived together as a family - it is that people are related. I mean, no one cringes if you **** the neighbour next door who was like a brother to you when you grew up. Even though the social dynamics in that relationship might have been exactly like a sibling relationship would be. What makes it a taboo is that you are related to someone. He came out of that woman's vagina, that's what makes it disturbing - not that she'd older, I couldn't care less about that (nor that a woman in her 60s has sex - I sure hope I do when I'm that age).
