Sunday Times Teaser 2589 – A Certain Age

Published: 6 May 2012 (link)
My cousin and I share a birthday. At the moment my age, in years, is the same as hers but with the order of the two digits reversed. On one of our past birthdays I was five times as old as her but, even if I live to a world record “ripe old age”, there is only one birthday in the future on which my age will be a multiple of hers.
How old am I?
