Mine is Sept. 24, 1968
Erika has the same Birthday as me but a different year. I never thought I could be 12 years older than anybody.
Tsk tsk tsk. That’s Canadia day, where our slogan is: Canadia. The other North American country.
I count three September 18th’s here, cheezit in 1948, me 1958, and Nimue in 1978. Ok, where’s that other Virgo, the one from 1968? We need to complete a set here.
Dam, there’s a lotta young whippersnappers round here!
12-9-62 for me. Only 81 shopping days left!!!

Okay, I’m bored. Also, I did not double enter so I cannot verify the accuracy of the dataset. But one thing is obvious…
We need more old farts.
October 1st, 1960. How the hell did I get here so fast!
…And your definition of ‘old’ is…?
Let me restate that, what is the cut-off year for ‘young’ vs. ‘old’? Just so I know where I stand before I post back.
February 15, 1970
June 26, 1971. The United Nations, Pearl S. Buck, and my Aunt Shirley are lucky enough to share a birthday with me. That’s it, as far as I know.

Well, since my own data point is in the 1956-1960 category…the '60-61 point seems like a nice cut-off for me. 
So let me rephrase that: I’d like to see more delightfully young-at-heart posters like myself.

Old fart checking in: June 8, 1954, beating Spider Woman
And old enough to recognize your chart as being the sort of graph we used to get out of Visicalc. In my day we didn’t
[sub]have all these high-falutin’, graphically based …[/sub]
My birthday is also Sept 24, but I was born in 1970.
May 18, 1978…chinese: horse sun sign: Taurus w/ Gemini cusp.
