Time flies so fast 😞

I just saw a picture of some of the kids I used to play with maybe more than ten years ago now,
They were my cousin kids and they were around ten years younger than me, we were like friends they were my younger sibling age, and we all hang together a lot and we went on a holiday all together with my older sister as a chaperone , I haven't met them in ten years I moved away and I just saw them they literally had beards and were like six feet tall , and I was thinking did I just get older or is time flying so fast. I still have our pictures on my phone from our last trip when they were kids and I was maybe in high school.
