That's informative. In fact I bet physiology plays a strong role in our preferences whether or not we consciously realize it.

I was watching a documentary lately where some group of fish spent days climbing up the rock behind a waterfall with very low rates of success to lay their eggs. It felt incredible some code in their genes affects them at a point in their life where their utmost goal becomes swimming upstream no matter the dangers and they prefer doing that to, well, enjoying life in the sea.
