The individual gives a definite allegation as to DB and, according to that allegation,
is about age 65 or younger. The person is unable to submit any evidence of the date
alleged. However, some of the documents submitted (or obtained) indicate that the
person was under age 65 during all or part of what is established as the person's
actual IEP. Since this situation is comparable to that in Rule b. (i.e., the person
does not know when the person was born), Rule b. will be followed.
