I made a hacky little AppleScript to sort through the birthdates for the 90 of my 784 contacts (11%) where I have record of something. Of those 90 contacts:
- 41 are older than me (45%)
- 4 are the same age as me (5%)
- 44 are younger than me (49%)
So I think that means I am neither old nor young but rather just right.
