Old photos are basically evidence from a parallel universe. You look at them and genuinely cannot connect the dots between that version of you and the one currently holding your phone squinting at the screen.
Scientists call it "memory reconsolidation." Fancy talk for the fact that your brain quietly rewrites your past every single time you think about it. Like a sneaky editor who keeps changing the manuscript without telling the author.
But here is the part nobody talks about. A huge chunk of that mental fog has nothing to do with nostalgia or lighting or how questionable your hair choices were in 2009. It is about timing. Because your brain before coffee is basically a loading screen. Spinning. Going nowhere. Technically alive but not really functional.
