Ah, your question brings to mind the Year 2000 problem, which was due in part
to the custom of using only two digits to specify a year.
If no one was born in this century, then:
=DATEDIF(DATE(LEFT(A1,2),MID(A1,3,2),MID(A1,5,2)),TODAY(),"y")
But that may only be true for an unknown number of years, so you are going to
have to supply the possible age range for your persons in order to devise a
formula that will continue to work for the foreseeable future, or change your
ID's to use four digit years.
