Somehow, I'm still alive.

I keep seeing people born as late as 2008 walking around looking like full-grown adults, and honestly? it genuinely makes me wonder how I'm still alive. I’m over here finding grays and doing the math on whether my life is officially half over. Meanwhile, kids born as recently as 2012 are somehow pushing over six feet tall. Is this some kind of sci-fi dystopian timeline, or is this just what aging feels like?
