I took it twice.. the first time based somewhat on preferences and I was off by 13 years younger. The second time with what was out during the time I was growing up and with some preferences but not as much. My birthday is next month and that is how old they called me; it was absolutely right on this time. The irony is is that many of the categories I would have picked would have been "none of the above" or "other" or to fill in; I'd be curious how that would have come out.
