Please tell me, how many times did we have to disambiguate two
developers using the same name?  Even if we ever have to do that, do you
really think we'd use one's birthday all over the place?

a. 'Legal age' may differ per country, so birth date alone is not very
useful.

b. There is no reason to store the full birth date if all we need is
a boolean whether someone is of 'legal age'.

c. We don't even have any clue what to do if someone is *not* of 'legal
age'.
