French woman, 91, gets her PhD after 30 years

A 91-year-old woman has become the oldest person in France to get a PhD after taking 30 years to complete her thesis.

Colette Bourlier successfully defended her work yesterday before a jury in the University of Franche-Comté in Besançon, saying that she "took breaks" from writing her thesis which is called 'Immigrant workers in Besançon in the second half of the 20th century'.
