I'm 32 and I think last year I began noticing it.
Not just mentality, but mannerisms, actions/interactions - bit by bit it's falling in to place. I'm thankful for still having hair although a few rogues on the sides which are white/gray along with my dark hair which is still dark/almost black, but ''not Chinese black'' as my pal once described it are there, but those old rogues do stick out, but no one warned me about puggy/massive features, and EVER growing nose AND lugs which were already big enough when I was a child plus forehead lines.
Anyhoos, avoiding bars with loud music, being told you look like someone's uncle, subbed after 60 minutes or now just being constantly on the bench even though this is the fittest I've ever been since 16.
The hardest part of it is meeting kids born 12 years after you and still thinking they are the same age. My work pal is 19 and even now at this grand ol' age I wish I was as mature, coherent (did I even spell that richt?) and just on the ball as he is.
Maybe this is a self-confidence thing, but yeah,
When did you FIRST feel old, old?
