Talk:List of oldest living men/@comment-30591055-20161207090537

Allen Charles Jackson and his twin brother Allan Ceascear Jackson born 24 NOV 1903 have been known as two of the oldest twins ever. Allen Charles seems to not have been confirmed deceased, isn't he still living, the why is he not verified as a living supercentenarian? If he really is still living, he is the 2nd oldest man behind Israel Kristal.
