Being young isn't about age, it's about being a free spirit. You can meet someone of 20 who's boring and old, or you can meet someone of 70 who's youthful and exciting. I met Fred Astaire when he was 72 and I was 21, and I fell in love with him. He certainly was a free spirit.

Insight: There's something quietly radical about this idea that youth isn't really about how many candles were on your last birthday cake. We're taught to chase it like it's a finite resource that expires at 30, but what Van Dyke is pointing at is something harder to lose: the willingness to be curious, to try things, to not settle into the comfortable grooves of "that's just how people like me act." The trickier part is recognizing this in real time. We've all known someone their own age who seemed weary and closed-off, and someone much older who still had this spark of genuine interest in the world. The difference usually isn't metabolism or gym membership. It's usually whether someone decided that surprising themselves was still worth the effort. It's asking the dumb question anyway. It's changing your mind about something. It's dancing when you're 72. What makes this observation stick is that it works both ways as a warning. You can spend your twenties playing it safe, checking boxes, being exactly who you think you should be. Or you can stay attentive to what actually fascinates you, even when—especially when—it seems impractical. That's the choice that keeps you young.
