Thanks for pointing this out! I can't imagine why I did not think of this.

I am not in any way an endorser of trying to make code as short as
possible but out of curiosity I fixed my one-line class so that it now
correct but "unreadable":

def age_at(date, dob)
  date.year - dob.year - (date.month-dob.month < 0 ? 1 :
date.day-dob.day < 0 ? 1:0)
end
