Somebody just referred to a software tool (GIT) released in 2005 as old.  I used a predecessor (SCCS) in the late 70's that was released in '72 and still considered it fresh when I moved on to its successor (RCS) in the mid-80s.
 
<sigh>  - LOL

I keep thinking the 90's was 10 years ago. 

I still feel 29 (in my head) except when I crouch and then I try to get up.

I remember when 1984 seemed like the distant future, but HEY... at least I am not as old as I feel! That's something I guess. I'm thinking I should stop taking drugs and start abusing them.

I'm officially MOLD.
 
I've been left out too long.

That's a good point.  The older we get the less we have to worry that bad habits will shorten our lives!  ;)

I still remember paying $540 for a 10 MB hard drive.
(Though that seems expensive for 2009...)

I too have concluded that I seem to be getting old.  
 
I was less impressed by the fact that no one seems to appreciate my primitive acquaintance with Fortran, than with the experience of having my "Good morning," offered to a bright young lady, rejoined with "Get lost you fat creepy old man."

How about IBM's PLI language that tried to combine Fortran with COBOL?

Saw this on a T-shirt about a year ago:
 
Inside every old person is a teenager crying out "What the Heck Happened!?!?!"
 
I would say the guy wearing it was in his 60s
