"A new study by Ben Gurion University shows that 52% of Israeli journalists who have covered terrorist attacks suffer from post-traumatic stress disorder, to the extent that they need therapy. The figure for journalists is 5.5 times higher than it is for the general population, where post-traumatic stress affects 9.4% of the population."
I can't say as this surprises me, but the numbers are still shocking. I've met combat photographers who were permanently traumatized by their experiences. And many war correspondents find themselves in close proximity to combat or directly in danger.
