Going to join the 30s club myself soon.
Not that my physical age seem to matter. The people who know me in person describe me as a "grouchy grampa", and I still get asked for my ID at cinemas ("Dude... I'm like almost twice your age...")
Random Auntie: "So what school are you in now?"
Me: "..."
I suppose I'll consider it a blessing when I turn 60 and people still think I'm 30 or something, but man can it get annoying at times.
Cheers.
