Epigenetics and mother's body influence feel - to me - like magic more or less the same. And the nature vs nurture regarding tastes developed either early or later on, well, as a father of 2 siblings who are radically different in certain tastes, I don't really know where I would have nurtured them into being different. I try to introspect a lot on that, maybe we did something but honestly... I don't think so.
