when all the crazy stuff i did caught up to me and i couldnt do a lot of things anymore. my mom always told me to be more careful. she said all the things you do to your body will come back to you one day. i thought that was some bogus nonsense...i should have listened to my mamma! lol

Not sure if it was the first time, but when I went to the doctor's office, and the doctor came in and he was a good decade younger than me!

never, dear, never.....

My kids make me feel old a lot but that's normal. One thing that makes me feel old without their influence is singing along to grocery store music. I was in Wal-Mart the other day and heard Anne Murray and I was so excited because I hadn't heard her for so long, I forgot she even existed!

Probably not the first but last weekend Iwas eating near a hotel and saw a LOT of attractive teenage girls and thought "these are kids" ..

It is as I had suspected, I have been old for many decades. How does this happen?

Old? I still think I am a kid, though my body and some othe prople point out otherwise. I have a 9 year old daughter who is too often mistaken as my grand daughter. I was at the park with her and another parent with her kids and additedly she looks young next to me. But another little kid asked is she could play, being a parent she tried to decline and the kid said "you could ask your dad, pointing at me"
THAT is when I realized I was old.

I realized it when I walked passed a cemetery and two guys started chasing me with shovels.

When I went out and tried to pick up a 20ish young woman and she give me the look plus a EeWW! ?

when i did the pogo for 2 hours and couldn't walk properly the next week [ last week after orchestral manuvers in the dark]

When hair started growing out of my ears

As I read your question it occurred to me.

Oh shit! I am old.

Thanks for that.

When my friends started making babies on purpose.

I remember listening to "Lunchtime with the oldies" on the radio while I was at Ft. Meade, Maryland. I was in my early 20s, and they played a song that I loved in high school. I was pissed about that for days! And that was the first time I realized it was really all downhill from there. My middle daughter freaks out about wrinkles and turning 30! I told her "really? Every wrinkle and grey hair I have has your name on it" I may be old, but I don't care! I'm OK with it. My mom died at 45, she never got to meet her grandchildren or see any of her kids get married or any of that other cool "getting old" stuff. Your age is just a reflection of the number of trips around the sun your have made. Don't let your age define you. I may be 60 and my knees make some odd noises and yes I have a few gray hairs but dammit, I put the time in for it. I earned it! I am happy about it because so many don't get that opportunity. JMHO ( or not so H)

When I was admiring the skills of cute little middle schoolers in a marching band parade, then realized they were university students. Ooops.

When I could no longer have sex twice in quick succession!

If you think your too old then you are.

Most days I haven't gotten there yet. Maybe when I'm 70 I'll think I'm old.

When I got my knee replaced.

I never really liked going out lol

When it took two days to recover from a hangover. ?

I'll add something to an earlier answer. I resist the idea that I'm getting old but it is getting increasingly difficult when my 11 year old groups dinosaurs, the stone age and me and being around at the same time.......Love you

When my knee started hurting before major thunderstorms. And my Gibson ES-175 keeps getting heavier....

I haven't yet..so tell me what's it all about?

If the secret is "weekend out"....dear, I am a teenager; I go out every day.
