It's weird that we enjoy stimulating our fear response
What would aliens think if they leaned we evolved fear as a survival mechanism, but we intentionally seek out situations that trigger our fear response, for fun?
Horror movies, extreme sports, thrill-seeking, it's all weird.
Edit
Changed the title and added an extra line to make it clear I'm talking about the fear response, and not specifically about extreme sports
They would think that we create sport out of pushing our physical limits so as to advance our physical limits at an optimal pace.
