Many Happy Returns!
I don’t know what this has to do with me, but happy birthday just the same! 
Looks like the median Doper is about 39 years and 10 months old.
I’m 57, but I doubt I look like I’m old enough to be Onomatopoeia’s dad. People are surprised to find out I’m over 50.
I’m 61 and the oldest in the SDMB poker group. They make sure to remind me every now and then. They throw a pot or two to the old guy out of pity sometimes.
47 ish… old enough to know better and young enough not to care.
I am old enough this year to know the meaning the life, the universe and everything.
So 42.
Really, I’m in the best shape of my life, in school, my kid’s heading towards college, my husband is awesome and my life is really very amazing.
I just wish this had started at 22, so I’d have more time to enjoy it!
I am fourteen years of age.
Looks like they voted in Giles’ poll from last year too. Alright, which one of you clowns is it?
26, lurking since I was 15 or so.
What a delightfully normal distribution - although you picked extremely odd age brackets, since it virtually drops off at 60+. That should have been a single category, with finer gradations in the age ranges below it.
We’ve switched Jaledin’s favorite decaf brand with Starbucks High Output Megacaf Ultracondensed Espresso. Let’s see if he notices…
Happy Birthday!
This post is a thing of transcendant beauty and I humbly bow before its awesomeness.
Twenty-six.
Fifty three.
I’m 41. The greatest reward? Looking younger than I did at 31.
I don’t get it.
61
Here’s a comparison with the results from the poll Giles posted a year or so ago:

Draw your own conclusions about what this means.
Note that this thread is only 105 voters short of that poll last year, and that last year poll had the most voters in any poll that I have been able to locate!
Now that was impressive. Zeldar, YOU tha MAN. 
(I searched your name in the “what’s your gender” threads to be able to write this post.)
It makes sense that it got the most voters. Not everybody has an opinion on fashions or cilantro or whatever. But age is, after all, something that everyone here has.
