When did you realize you're becoming "old"?

When many of the films, or tv programs being made are reboots of programs i watched as a teenager.
Pop singers you liked are now on classic hits radio .
When people in shops call you sir.
Do kids these days know who bosco is ,
or what the den , old kids program was.

When I clicked into this thread

Save me Jebus, I must be ....

When I realized I had pre-programmed Radio 1 into my car stereo!

My sister also told me I'm old now because I said I don't think these new dessert creations with loads of chocolate and cream and donuts on top of milkshakes look appetizing

When you see a 20 something year old and her mother walking up the road and you think the mother is hot.

Went to a nightclub for the first time in about 18 months on Saturday night. My ears were still ringing until Monday morning ... I'm 31.

Playing ps2 games and remembering when they were released

Thinking a 00 car is still fairly new

When you're missing a few teeth

Few kids playing football and ball ended up being kicked in my direction whilst I was walking past. Got a shout of "hey mister, can you kick our ball back"

That was the exact moment.

When you start cutting back on sweets / crap food because of cholesterol

When you sit on your own balls ;-)

I remember in about the year 2002 and I used think that 1992/1993 cars were old. Now I look at 1999/2000 cars and I say to myself they're nearly new. I also remember looking at cars online which were about €22,000+ in around 2005 and now there selling for under €1500.
When I look back at year year 2000 and I think of the people who turned fifty and now there pensioners and the people who people who became pensioners in the years 2000 are now in the eighties.
When I relies the kids in school now can't remember/weren't born when 9/11 or the 7/7 bombs or Irish stories such as Rachel O'Reilly murder, Catherine Nevin, John Gilligan being jailed or the Omagh bomb.
When I relies that programmes such as Lost and Desperate Housewives first aired nearly twelve years ago!
