I'll chime in here, too. I'm 40, and have owned my 99 base since last August. As far as the stats go, I have a bit to contribute (I'm a statistician by profession):
Summary Statistics
Mean 44.397059
Std Dev 13.141185
Std Err Mean 1.5936027
Upper 95% Mean 47.577903
Lower 95% Mean 41.216214
N 68
Median 44.5
Mode 44
It looks like we're a fairly normally distributed bunch, except for you guys in your 20's... but hey, I'm not sure ANYONE in their 20's is quite normal.
Cheers,
Jason
