Do you know the critical information about your own birth? Do you know what your Apgar score was? Were there any complications during or immediately after delivery? How about your childhood immunization record?
Most adults don't know the answers to these and many other childhood healthcare related questions. Some of the details of the treatments and conditions you had as a child may impact your health later in life. Unfortunately, this information is typically unrecoverable by adulthood, since most records cannot be reconstructed.
