This is a great post! I am certainly no expert on genes (though I recognize a nice pair of them when I see them), I've always subscribed to the nature and nurture team. Genetics certainly does determine a lot of things, but it doesn't define us. Environmental factors also come into play, and that's been proven too. You have a great balance here. More depth could serve a larger purpose, but you explain complex topics real easily. That's admirable.
