"Where did we go wrong?"

I'll tell you.

Nature vs. Nurture.

Debate it all you want, but everything determined by our genetics. It is shown over and over again, you can even predict who will be more likely to be in a car crash based on genetics. Score one for nature.

However, similar studies have shown that you can also predict just about everything that might happen to a person based on their environment that they live in. Score one for nurture.

We went wrong on the "nurture" front. Something happened in your life. Maybe it was a trip to the zoo, maybe it was the croc hunter, maybe it was growing up in the southeast and playing in swamps. Just because you don't remember how you first started liking reptiles doesn't mean there wasn't an environmental cause (or a few)
