The Oldest Living Biological Memory

The 'Oldest Living Biological Memory' is based upon the oldest living person and whose mother had a later in life pregnancy.  Although this person is not the officially born oldest, speaking from a biological cellular point of view, their cell may have formed on this planet much earlier than the oldest person on the planet.

We do not know who has the 'Oldest Living Biological Memory' but famous contenders for this title include: Stan Lee, Louise Ranier or Kirk Douglas.  It is possible that the man on the five dollar bill was president when their first cell formed,  and that president would have been Abraham Lincoln.

Improbably, but not impossible.  Certainly someone on this planet had their first cell form during the Lincoln Administration.
