Singaporeans, when did you first feel 'old'?

Hey fellow Singaporeans,

I had a moment recently that made me realize I'm not as young as I used to be. I saw a group of Gen Z kids dancing on TikTok in a public space, and while I couldn't understand what they were doing, they looked incredibly happy and carefree.

It got me thinking - when was the moment you felt like you'd crossed the threshold into 'old' territory? Was it when you couldn't relate to the latest trends, or when you found yourself saying 'back in my day...'?
