Hopefully I won’t kill this thread too.
I figure I have a 75 year old knee, and a 25 year old … soul (what’d you think I was going to say).
So my average age is 50. 
- Crap, I’m older than average.
I just turned 20 for the second time, i.e., 40.
and I am not a straight Doper.
Just doing my part to drag the curve up.
As an actuary, I’m weeping for the lost opportunity to get people to post their date of birth rather than age. Data is king, dude - always go for the max, not the minimum you can get. Date of birth allows the calcuation of precise age.
The way you have it in this thread, if someone says that they are aged x then all you know is that their actual age is in the interval (x,x + 1]. That is, assuming that birthdays are uniformly distributed on the calendar year, on average their actual age is x + 0.5 *
That means that when you do your calculation and declare that the average dope age is 73.2, you should bear in mind that the actual average age is really 73.7.

Oh yeah - my date of birth is 1/12/1976
*Of course, in reality this assumption is false. More sex happens at certain times of the year, so birthdays are not uniform. For example, there are always more births on November 14th and the week before and after than at other times of the year. But the assumption is close enough for these purposes.
OK. Allowing for my above post, I put the numbers into Excel and used a half-year adjustment for anyone who hadn’t indicated their exact age (either with a birthday or saying “newly” or anything like that).
The sample average came out as… 33.1 years old
The sample standard deviation (unbiased) is… 11.9 years. So assuming the data comes from a Normal distribution, we should have about 2/3 of us in the (21.2, 45) interval and 95% of us in the (9.3, 56.9) interval. I see no reason to assume a non-skewed distribution however, so these intervals should be treated with extreme skepticism.

Yeah, seem to be us and young whippersnappers. The thirties seems under represented. I know it’s not because they have lives, because I didn’t when I was their age.
21!
31 and 4/365ths.
I’m 20 going on 6 and 80 all at once.
And just for kabbes, 3 July, 1981. (about 4:30 pm)
Everyone thinks I am either considerably older or considerably younger than I really am.

2 April, 1978
I’m 814,450,860 seconds old.
24 - no one else is 24. I feel … I feel pretty, oh so pretty, so pretty, and … um.
Dec 3, 1976.
Probably the scariest part is that I realized that as of about three months ago, I am now closer to my 30th birthday than I am to my 18th.
Some people have panic attacks about “the big 3-0”. I’m having a panic attack at being closer to 30 than 18.
