I'd agree with you, but as soon as I came back to live in the city, my nite-owl tendencies returned with a vengeance. It was like flipping a switch.

I'm also not trying to generalize to everyone, I'm only surmising that there may be a lot of people like me. It's arrogant to assume your personal experiences apply to specific other people, but it's equally arrogant to assume you're a snowflake and that other people's experience is irrelevant to your situation. Everyone is their own unique blend of the many human commonalities.
