The movie The Karate Kid made me feel old.
When I was a kid, I remember watching the karate kid and seeing Mr. Miyagi's car collection and thinking those cars were old as hell. According to my dad, the one Daniel drove around in was a '47 ford. So that movie came out in 1984, which would make that cherry Ford 37 years old then. A 37 year old car today is a 1987 model year. YJs, 1st gen 4runners, and my parent's Suburban now suddenly are as old as that ford was when I watched the movie as a kid.
Waking up sore from doing things that didn't make me sore, or having gray hairs, or even young dudes at work dont make me feel old. Thinking some kid is viewing at a 1987 4runner the same way I viewed 1947 ford makes me feel old.
