I'll be 43 in a few days....
I actually liked the number 37.  A good number.  And, it isn't a young '30s {so you've been in the 30's hood for a while and have that experience}  and you aren't 40 {although my 40th was fun spent at Disneyland proudly proclaiming my age on my birthday sticker}.
Okay.  But, honestly, I won't ever ask anyone to guess my age.  Ever.  
I doubt if I would be as lucky as you are with Alexs' guess.
