2006 was only 4 years ago, right? RIGHT?

Still though, the average age in the US is 38 so for most people, there was an amendment ratified during their lifetime.

Speaking for me personally, I would consider anything that happened in my parents generation to be a recent collective memory, at least until I get to the age my parents were when they had me. Sure I wasn’t alive during the moon landing or JFK assassination, but they’re still pretty recent events in the grand scheme of US history.
