His PhD lasted 13 years

We all know that PhDs can take longer than the 3-4 years nominally allowed for completion. It is not uncommon for PhDs to take 6 or 7 years or even longer, and successfully completing a PhD may be as much about stamina as academic ability. So, if you find yourself struggling with the length of time that it is taking you to carry out your research, take heart from this story, by Neha Miglani in the Times of India, of a PhD that took 13 years to complete.
